A bubble of 8 mole of helium is submerged at a certain depth in water. The temperature of water increases by `30^(@)C`. How much heat (in Joules) is added approximately to helium during expansion

A

4000 J

B

3000 J

C

3500 J

D

5000 J

Text Solution

Verified by Experts

The correct Answer is:
D
`Q = nc_(p) Delta T = 8 xx (5)/(2) xx 8.31 xx 30 " "[as C_(p) = (1 + f/2)R]`
`= 4988.4 ~~ 5000 J`.
