Is it true that temperature is the measure of the average kinetic energy of the particles in an object?

Answer 1

For the "ideal gas" kinetic theory gets the following relation:

Ek = 3/2 RT

where Ek is the average molar kinetic (translation) energy, R the universal gas constant and T the thermodynamic temperature.

Solids molecules or atoms don't have translation energy, changes in their internal

energy are given by changes namely in their vibrational energy components.

Answer 2

Temperature is a measure of the average kinetic energy of the atoms in the object. The atoms may or may not have the same mass, but I know for sure they do not all have the same velocity. When they bounce off of the wall of their container, they may lose or gain some KE. When they bounce off each other, they may lose or gain some KE.

KE = ½ * mass * velocity^2

Answer 3

Yes - more or less. At least, that's a good approximation. Actually, it is a bit more complicated.

Answer 4

No, the amount of energy depends on other things as well, like the mass of the object.

Answer 5

yes: temperature is a measure of the average translational kientic energy of motion of the molecules in a object.

Answer 6

yes

Answer 7

Yes
