What does the thermal energy of matter depend upon?

a
Temperature, only
b
Number of particles, only
c
Mass, number of particles and temperature
d
Mass, only

c

Mass, number of particles, and temperature. The thermal energy of matter depends on the kinetic energy of its particles, which is determined by the mass of the particles, their number, and their temperature.

The thermal energy of matter depends on the mass, number of particles, and temperature. The correct answer is option c.
