Chapter 23, Problem 37A

If a large tub of water is kept in a small unheated room, even on a very cold day the temperature of the room will not go below $0°C$. Why not?

To determine

To Explain: The temperature of the room does not go below $0°\text{c}$ on even very cold day.

Answer to Problem 37A

The freezing water releases $80\text{cal/g}$ energy that keeps room’s temperature going below $0°\text{c}$ .

Explanation of Solution

Introduction: The physical quantity, which expresses hot and cold, is known as temperature. It demonstrates the thermal energy that present in matter.

The freezing water continuously releases energy of $80\text{cal/g}$ that keeps the temperature of the unheated room going below $0°\text{c}$ , even on a very cold day.

Conclusion: The continual release of energy from the freezing water prevents the room’s temperature going above $0°\text{c}$ .
