What does the thermal energy of matter depend upon?
a
Mass, only
b
Number of particles, only
c
Temperature, only
d
Mass, number of particles and temperature
1 answer
d. Mass, number of particles, and temperature all contribute to the thermal energy of matter. The thermal energy of a substance is a measure of the total kinetic energy of all its particles, so the more massive the substance, the more particles it has, and the higher the temperature, the more thermal energy it will possess.
