Question

Akeem is walking on the beach on a hot summer day. The sand is very hot, so he runs and puts his feet in the water, which is much cooler. Explain why the water is cooler than the sand.

Answer 1

Answer:

The water is cooler than the sand because it has a higher specific heat value. This means that it takes longer for the water to increase in temperature, making it feel cooler than the sand, which warms up more quickly.

• It takes longer for the water to increase in temperature.
• The sand has a lower specific heat value.
• It takes less time for the sand to increase in temperature.
