Question

calculate the ratio of kinetic energies of 3 grams of H2 and 4 grams of O2 at given temperature​

Answer 1

if the temprature is constant then kinetic energy wil be the same the ratio willl be 1:1

Answer 2

Kinetic energy depends on temperature i.e., it is directly proportional to temperature.

Since temperature is constant, therefore kinetic energy of both is the same.

Ratio of kinetic energy=1:1
