# At What Temperature Will Average Kinetic Energy of Gas Be Exactly Half of Its Value at N.T.P.? - Physics

At what temperature will average kinetic energy of gas be exactly half of its value at N.T.P.?

#### Solution

Solution:
Kinetic energy of gas = 3/2RT

K.E prop T

(K.E)_2/(K.E)_1=T_2/T_1

1/2=T_2/273

T_2=136.5K

At 136.5 K, the average kinetic energy of the gas will be exactly half of its value at N.T.P.
