Question

Equal volumes of monoatomic and diatomic gases at the same temperature are given equal quantities of heat. Then

• A. the temperature of diatomic gas will be more
• B. the temperature of monoatomic gas will be more
• C. the temperature of both will be zero
• D. nothing can be said

Answer 1

Answer: (B)

the temperature of monoatomic gas will be more

Answer 2

Energy required to increase the temperature of one mole of monoatomic gas by $\Delta T =3 / 2 \times R \times \Delta T$ Energy required to increase the temperature of one mole of a diatomic gas by $\Delta T =5 / 2 \times R \times \Delta T$ So, for equal volume i.e. equal moles equal amount of heat will increase the temperature of a monoatomic gas more than the diatomic gas
