Question

Fourth full. She then places a small, heavy cup inside the glass bowl. The cup is heavy enough that it does not float. She makes sure that no water enters the small cup when she places it in the bowl. She then places the oven-safe bowl with the water and cup on an electric burner. Finally, she turns the burner on to low.

Answer 1

Part A

What will happen to the water in terms of phase changes when Marisol turns on the stove?

When Marisol turns on the stove to the lowest setting, the water in the glass bowl will boil and there will be small bubbles floating on the surface of the water and steam will rise
Part B

Marisol covers the bowl with plastic wrap and then places ice on top of the plastic wrap. Write a hypothesis predicting how the plastic wrap and ice cubes will affect the water vapor in the large bowl.
At that time, when the steam rises, it will condense on the surface of the food wrap but Marisol has put ice on the surface of the food wrap, so the steam will accumulate on the surface of the wrap and cannot condense because of the cold vapors of the ice above. The cold ice will melt into the water due to the heat of the stove and after the ice melts, the steam will start to condense on the surface of the food wrap and then the water droplets on the wrap will gradually drip onto the glass of water inside the glass bowl.
Part C

The image shows what happens when Marisol completes her setup.Write down what you observe in the image. Explain the processes that occur in the bowl and result in what you see.

I have explained that in part B, you can see it.

Answer the following questions about Marisol's model.

Part A

Does what you observed in the model (part C, above) support your hypothesis from part B? Why or why not?

No, I feel it is different from my hypothesis. When the ice has melted, the steam will condense on the surface of the food wrap and every drop of water will fall but the image shows that the cold ice has not completely dissolved but the drops of water also falls from the wrap.

Part B

Why is it important to heat the water for this investigation? What heats the water in the oceans, lakes, and rivers found on Earth?

The water in ocean, lakes and rivers are heated by the Sun, sunlight hits the ocean which is dispersed by the first 1000 meters of the ocean's surface. This hot water is mixed with the cold water at the bottom of the ocean by ocean waves and this is the reason why ocean waves are at a regular temperature.

Part C

In this experiment, the bowl of water represents the ocean. What does the plastic wrap represent?

The water in the base of the bowl represents the ocean. Over time the heat from the sun will cause this water to ​evaporate​. The ​water vapor​will rise and ​condense​on the surface of the plastic wrap, which represents the clouds.

Answer 2

The water in ocean, lakes and rivers are heated by the Sun, sunlight hits the ocean which is dispersed by the first 1000 meters of the oceans surface. This hot water is mixed with the cold water at the bottom of the ocean by ocean waves and this is the reason why ocean waves are at a regular temperature.

In a lake the water is heated the same way but there is not much water to mix the hot water with the cold so the water in the lake seems hotter than the ocean.

In a river the water keeps on flowing which mixes the hot water with the cold and the temperature remains regular.

Step-by-step explanation:

Sound is a wave which is created by vibration, and these sound waves can travel in different mediums for example, air, liquid and even solid.

The water in ocean, lakes and rivers are heated by the Sun, sunlight hits the ocean which is dispersed by the first 1000 meters of the oceans surface. This hot water is mixed with the cold water at the bottom of the ocean by ocean waves and this is the reason why ocean waves are at a regular temperature.

In a lake the water is heated the same way but there is not much water to mix the hot water with the cold so the water in the lake seems hotter than the ocean.

In a river the water keeps on flowing which mixes the hot water with the cold and the temperature remains regular.
