Chapter 5, Problem 7STP

To determine

To Choose: The correct option.

Answer to Problem 7STP

Option B: The law of Convection follows.

Explanation of Solution

Introduction:

In convection, the heat transfers from high energy concentrated region to low concentrated region in liquid or gas.

In heating the water, convection rule follows in which the thermal energy transfers from warm region to cold region through air particles. This kind of heat transmission requires no physical contact as required in conduction. The molecule of water evaporates in air and the heat transfers through it.

Conclusion:

Hence, the law of convection follows when the water is heated.
