The materials used in the demo were two beakers, a hot plate, water, and food colouring.
After two drops of the food colouring were added to each beaker of water, the drops in the cold water spread out but only settled to the bottom of the beaker, and the drops in the hot water stayed throughout the water, turning it all red.
Since the molecules in the cold water would be moving more slowly, the food colouring diffused more slowly throughout the water. The hot water molecules are moving about more rapidly, causing the food colouring to diffuse more rapidly througout the water.
MATERIALS: 2 beakers(same size), water(same amount in each beaker), hot plate, and red food coloring
OBSERVATIONS: When a few drops of food coloring were added to each beaker, the food coloring sank to the bottom of the one with the cold water but stayed at the top of the beaker with the hot water. Also, the food coloring diffused faster in the hot water then the cold water.
EXPLANATION: The reason for the food coloring sinking to the bottom of the beaker with the cold water and not the hot water is because when water is colder it is more dense as well. And the reason for the food coloring diffusing fast in the hot water than the cold water is because the water particles move faster when they are hotter.
In this demonstration, Ms. Wenk used 2 beakers with equal amounts of water in them, a hot plate, and food coloring.
First, she added the food coloring to the cold water and it sank to the bottom and did not mix. In the hot water, when the food coloring was added, the color spread out very quickly and moved through the whole beaker.
When water is heated, the molecules move much faster, which causes the molecules of the food coloring to speed up as well. In the cold water it is the opposite. The cold water's molecules move slowly and cause the molecules of the food coloring to slow down. This makes the food coloring spread out at different rates.
The materials that Ms.Wenk used in the demo were two beakers, a hot plate, water, and food colouring.
She put a drop of water in a beaker of cold water and in a beaker of hot water on a hot plate.
Since the water was heated the food coloring molecules spread quicker then in the cold water since in hot water the molecules moved faster then in the cold water where the molecules were mvoing slower. So since in one the molecules were moving faster in one then the other. The food coloring spread at different rates.
The first step Ms. Wenk performed was adding the food coloring into the cold water beaker. All that happened was the food coloring floated and didnt diffuse throughout the liquid. This is because the molecules in the water are moving very slowly. Next, she added the food colorung to the warm water and it diffused through the liquid much quicker than the cold water. This is because the water molecules are moving much quicker and can carry the color though the liquid. The temperature of the water effects how fast the food coloring spreads or diffuses through the water.
Materials used: 2 beakers, water, red food coloring, & a hot plate.
The food coloring mixed with the water more quickly because the molecules in the hot water are moving more quickly (this is how you heat up food in a microwave - fast moving molecules create heat). however, the cold water has slow moving molecules and therefore won't mix with the food coloring as fast.
Materials: 2 beakers the same size, filled with equal amounts of water. red food coloring, and a hot plate. In this demo Mrs. Wenk used one beaker filled with cold water, and one filled with water heated on a hot plate. She added 2 drops of food coloring to each beaker, first to the cold one, and then to the heated one. Once she added this, the die started to spread out quickly in the heated one and turned the water red. Although, in the cold one the red stayed mainly at the bottom and slowly started to spread out. This is because the molecules in the heated water are moving at a much faster pace, which allows the red food coloring to spread out much faster. The reason it took longer in the colder one is because the molecules are moving slower, the rate at which the molecules are moving is affected by the temperature of the water.
MATERIALS: 2 beakers of the same size, equal amounts of water in the beakers (one filled with hot water, the other with cold water), red food coloring, and a hot plate
OBSERVATIONS: First, Ms. Wenk put two drops of red food coloring into the beaker filled with cold water, and then she put two drops into the beaker with hot water. The food coloring in the cold beaker spread out a bit, but then slowly sank to the bottom of the beaker, where it stayed. The food coloring that went into the hot beaker immediately spread out, and turned all of the water red almost instantly.
EXPLANATION: The molecules in the water move faster as the temperature increases. So, when you add something to the water, it will move slowly when out into the cold water, which is what made the food coloring spread out slowly and eventually sink to the bottom of the beaker. Likewise, when the food coloring was put into the hot water, it spread out very quickly because the molecules in the water were moving at a faster pace.
Materials: 2 Beakers, Hot Plate & Red Food Coloring
In this lab you have two beakers filled up equally with one beaker containing cold water and another put on top of the hot plate to heat up the water. You then put 2 drops of red food coloring in each beaker. The food coloring in the cold water didn't spread out in the water and sat at the bottom of the beaker because the molecules in the cold water move slowly. The two drops of red food coloring in the hot water spread out through the whole beaker really fast because the molecules in hot water moved much faster than cold water.
Materials: Two beakers, hot plate, water, food coloring
Observations: Ms. Wenk added two drops of food coloring to both hot and cold water. The food coloring in the hot water spread quickly. The food coloring in the cold water sank almost directly to the bottom and then started to spread back up very slowly.
Explanation: As temperature increases, kinetic energy increases as well. Higher kinetic energy means that the particles move faster. Therefore, the food coloring particles in the hot water move much faster than the particles in the cold water.
The materials used in this demonstration were 2 beakers, water, food coloring and hot plate. First Ms. Wenk put two drops of food coloring in one beaker that contained hot water and the other beaker that contained cold water. The food coloring spread quickly in the hot water and in the cold water it stayed in the bottom and it did not mix with the water. This happened because the molecules in the hot water are moving faster than the molecules in the cold water, therefore the diffusion in the hot water will occur sooner than the cold water and that is why the food coloring spread more quickly.
This demonstration included water, red food coloring, two beakers, and a hot plate. After the food coloring was dropped into the beakers, one with hot water and one with cold, the spreading of the coloring occurred at very different speeds. In the cold water, the coloring slowly sank to the bottom. Yet, when Mrs. Wenk put coloring into the beaker on the hot plate, the red dye quickly spread and mixed with all of the liquid in the glass. The red food coloring in the hot water moved more quickly because molecules move much faster in heated water. In the cold, molecules move slowly, causing the dye to move slowly as well.
Materials: 2 water filled beakers, a hot plate, and food coloring. In this demo Ms. Wenk took one beaker of hot water and one beaker of cold water. In each beaker she put one drop of food coloring and allowed them to both settle. The reason for the food coloring in the cold water sinking to the bottom and spreading slowly is because the molecules in the cold water are moving much more slowly. The food coloring in the hot water spread more quickly because the molecules in the hot water are moving quickly.
Materials used in this demonstration were two beakers of the same size, a hot plate, water, and food coloring. One beaker was filled with hot water, and the other one with cold water. First, Ms. Wenk put two drops of food coloring into the cold water and then put two drops of food coloring into the hot water. In the beaker with the cold water, the food coloring moved slowly to the bottom of the beaker with little food coloring in the middle. In the beaker with the hot water, the food coloring spread throughout the entire beaker and turned the water red. The food coloring in the hot water spread throughout the beaker because the water molecules were heated, making those molecules move much faster. The molecules in the cold water moved much more slowly, making the food coloring slowly move to the bottom of the beaker instead of spreading through the entire beaker quickly, like the hot water beaker did.
The materials used in this experiment were a hot plate, two beakers, water, and red food coloring. One beaker was on the hot plate (heating up) and the other was just cold water. Ms. Wenk put the food coloring in the cold beaker first, and the food coloring dissolved faster in the warm water. This happened because the water molecules in the warm beaker move much faster, so they were able to spread out faster. Whereas, the water molecules in the cold beaker move slower, so they take longer.
