An increase in thermal energy leads to _____

Question

a. a decrease in heat and a decrease in kinetic energy until a phase change occurs.
b. an increase in heat and a decrease in kinetic energy until a phase change occurs.
c. an increase in heat and an increase in kinetic energy until a phase change occurs.
d. a decrease in heat and an increase in kinetic energy until a phase change occurs.

Answer 1

An increase in thermal energy typically leads to an increase in kinetic energy of the particles in a substance, as thermal energy is related to the motion of particles. Before a phase change occurs, the temperature of the substance usually rises, indicating an increase in heat and kinetic energy.

Therefore, the correct answer is:

c. an increase in heat and an increase in kinetic energy until a phase change occurs.
