We are warmed on a hot moist day because water molecules in the air striking our bodies

Question

Quizplus · Accepted Answer

When water molecules in the air strike our bodies, they transfer some of their kinetic energies to us, resulting in a sensation of warmth. This is because kinetic energy is the energy of motion, and when two objects collide, they transfer some of their kinetic energy to each other. In this case, the water molecules with high kinetic energy collide with our bodies and transfer some of that energy to us, making us feel warmer. Option B is incorrect because gaining kinetic energy as they change state (from liquid to gas) does not necessarily cause them to warm us up. Option C is also incorrect because an insulating layer would trap heat and make us feel even warmer, whereas on a hot day we want to cool down.
