Question

Temperature is the average ______ of the molecules of a substance.

Options

• difference in K.E and P.E

• sum of P.E and K.E

• difference in T.E and P.E

• difference in K.E and T.E

Answer 1

Temperature is the average the difference in T.E and P.E of the molecules of a substance.

Hint: As total energy of a substance is equal to the sum of the K.E, and P.E of atoms (or) molecules
Temperature is equal to the average KE of molecules
K.E = T.E – P.E.
