If `R = ` universal gas constant, the amount of heat needed to raise the temperature the temperature of `2 mol` of an ideal monatomic gas from `273 K` to `373 K` when no work is done is

A

`100 R`

B

`150 R`

C

`300 R`

D

`500 R`

Text Solution

Verified by Experts

The correct Answer is:
C
c. `Delta Q = Delta U`
`= mu C_(v) Delta T = mu ((R )/(gamma - 1)) Delta T = 2 xx (R )/((5)/(3) -1) [373 - 273] = 300 R`
(as for monatomic gas `gamma = 5//3`)
