Imagine you are at your favorite beach. The sun is shining and you are enjoying the ocean breeze. The temperature is about 89F. You take your shoes off and realize that the sand is almost too hot to walk on. You run to the water's edge to wet your feet after the walk over the sand and realize that the water is almost too cold. Explain the temperature difference between the sand and water using Thermodynamics.

Answer:

Because the specific heat of water is much more than the specific heat of sand. So it will take more energy to raise the same amount of water, with the same temperature.

Explanation:

Step 1: Data given

The temperature = 89 F = 31.6667 °C

Specific heat of water = 4.184 J/g°C

Specific heat of sand = 0.290 J/g°C

The specific heat is the amount of energy needed to raise the temperature of a substance.

Specific heat of water >>> specific heat of sand

With other words, we need a lot more energy to raise the temperature of water than we need for the same amount of sand.

Because of the low specific heat of sand, it will raise in temperature (very) quickly, compared to water.
