Find total internal energy of 3 moles of hydrogen gas at temperature `T`.

Internal energy of n moles of helium at temperature T_1 K is equal to the internal energy of 2n moles of oxygen gas at temperature T_2 K then the value of T_1 /T_2 will be

Internal energy of n moles of helium at temperature T_1 K is equal to the internal energy of 2n moles of oxygen gas at temperature T_2 K then the value of T_1 /T_2 will be

The internal energy of one mole of ideal gas is

The internal energy of one mole of ideal gas is

The internal energy of one mole of ideal gas is

Internal energy of n_1 moles of hydrogen at temperature T is equal to the internal energy of n_2 moles of helium at temperature 2T. Then the ratio n_1//n_2 is :
