Think about visiting the beach on a hot day. Predict whether sand or water has a higher specific heat and explain your prediction.

Answers

Answer:

The sand has a higher specific heat

Explanation:

The answer is that the sand would have a higher specific heat than water because water requires a lot of heat to raise its temperature while sand needs less heat to change it as water has a high heat capacity that allows it to maintain its temperature within a range.
water has a higher SHC as it would be cooler than the sand meaning it requires more energy to reach the same temperature
