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
Solution
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.
