If you take off your shoes on a beach or any sandy environment and walk on it on a hot, sunny day, is the sand hot or cold?

The sand will be hot.

Explanation:

Mr. John will actually feel the hotness of the sand if he takes off his shoes on a beach or any sandy environment and walks on it on a hot, sunny day.  The sand will even be hotter than the water nearby since it takes more temperature to heat some water than it takes to heat the sand.

It may not be advisable for him to remove his shoes and start walking bare-feet on the sand in such a hot environment.

Hope this helps
