Question

Temperature is a measure of :
the average kinetic energy of the particles of a substance
the nuclear energy stored within the matter of an object or substance
the potential energy of a substance
the total kinetic energy of the particles of a substance
the thermal energy being radiated away from an object

Answer 1

Answer 2

nope, temperature is the average KE of particles of something
