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` is

A

`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))`

Text Solution

Verified by Experts

The correct Answer is:
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))`.
