The amount of heat energy required to raise the temperature of `1 g` of Helium at `NTP`, from `T_(1)K` to `T_(2)K` isA. `3/8 N_(a)k_(B)(T_(2)-T_(1))`B. `3/2 N_(a)k_(B)(T_(2)-T_(1))`C. `3/4 N_(a)k_(B)(T_(2)-T_(1))`D. `3/4 N_(a)k_(B)((T_2)/(T_1))`

Answer» Correct Answer - A
The amount of heat energy required.
`Q = f/2 nRDeltaT`
`implies Q = 3/2xx1/4xxk_(B)N_(a)DeltaT = 3/8 N_(a)k_(B)(T_(2)-T_(1))`.
