Which of the following processes involves a dispersion of energy?

A. The drop in temperature in a heated room when a window is opened
B. The conversion of heat to work in a combustion engine
C. Freezing raindrops on a leaf on a cold day
D. The work done by an air conditioner in cooling a room on a hot day

Answer :

A. The drop in temperature in a heated room when a window is opened involves the dispersion of thermal energy.

This involves the dispersion of thermal energy from the hot air inside the room to the cooler air outside through conduction and convection.

In thermodynamics, this process is a key example of energy transfer, where thermal energy naturally flows from a region of higher temperature to a region of lower temperature in an attempt to reach thermal equilibrium.

The correct option is A.
