select the correct answer. john is riding a ski lift to the top of wildcat mountain. he removes his gloves and rapidly rubs his hands together to warm them up. what happens when john rubs his hands? a. the skin on his hands rapidly conducts heat, similar to metal. b. he traps heat between his hands because skin is an insulator. c. the particles in his hands vibrate faster because of friction. d. thermal energy moves from his fingertips to his palms. e. he simulates a fever thatll raise his core body temperature.

Answer

Answer:

C. The particles in his hands vibrate faster because of friction.

Explanation:

Step1: Recall heat - generation by friction

When two surfaces rub against each other, friction occurs.

Step2: Understand the effect on particles

Friction causes the particles in the hands to gain kinetic energy and vibrate faster.

Step3: Relate to warming up

Increased particle vibration corresponds to an increase in temperature, warming up the hands.
