3. 7th Grade Heat Capacity
You are swimming in the ocean on a hot sunny day. The ocean feels very cold on your body. You take a swim on the same beach at night and the ocean is nice and warm. What is the best explanation for this?

4. 7th Grade Heat Capacity Answer
Water has a high heat capacity and holds heat in.
The wind moved the cold water away and replaced it with warm water.
Water has a low heat capacity and gives up its heat easily.
The energy from the sun is more spread out at night, warming the area.

24. 1,000,000 Question
How does our sun produce light and heat?

25. 1,000,000 Answer
The sun produces light and heat through fusion. The nucleus of two atoms combine and heat and light are created. Fusion is also the process that we use in our nuclear reactors.
