Question

1. describe the property of water that is indicated by the data. how is this property explained by the structure of water molecules and the bonds between them? type your answer here. 3. if you were to go to a sandy beach on a sunny summer day, which would feel warmer—the sand or the water? explain why, using your knowledge of the properties of water. type your answer here.

Explanation:

1. The heating - curve shows that water has a high specific heat capacity. Water molecules are polar and have hydrogen - bonding between them. Hydrogen bonds require a significant amount of energy to break, so water can absorb a large amount of heat before its temperature rises.
2. The sand would feel warmer. Sand has a lower specific heat capacity than water. This means that sand heats up more quickly than water when exposed to the same amount of sunlight. Water's high specific heat capacity allows it to absorb more heat without a large increase in temperature, while sand heats up rapidly under the sun.

Answer:

1. Water has a high specific heat capacity due to polar water molecules and hydrogen - bonding between them.
2. The sand would feel warmer because it has a lower specific heat capacity than water.
