Suppose `0.5` moles of an ideal gas undergoes an isothermal expansion as energy is added to it as heat Q. graph shows the final volume `V_(f)` versus Q. the temperature of the gas is `(use In 9 = 2 and R = (25)/(3) J//mol-K)`

A

`293K`

B

`360 K`

C

`386 K`

D

`412 K`

Text Solution

Verified by Experts

The correct Answer is:
B
` Q=W= nRT ln"(V_(f))/(V_(i)), T = (Q)/(nRlnV_(t)//V_(i)) = (1500)/(0.5 xx 25//3 xxln3) = (1500)/(0.5 xx 25//3 xx1)= 360K`
