Question

What will happen as an object receives energy due to heat flow? The molecules will move faster. The molecules will move more slowly.

Answer 1

The molecules will move faster

Answer 2

The correct answer is the first option. If an object receives energy from heat flow, the molecules of that object will move faster because temperature and kinetic energy is directly proportional. As the heat is added, the temperature increases therefore increasing the kinetic energy of the molecules resulting to a faster motion.
