The pressure p and volume V of an ideal ...

The pressure `p` and volume `V` of an ideal gas both increase in a process.

A

(i),(ii)

B

(ii),(iii)

C

(iii),(iv)

D

(i),(iv)

Text Solution

Verified by Experts

The correct Answer is:
B

`n=(P_1V_1)/(RT_1)=(P_2V_2)/(RT_2)`
`P_2V_2gtP_1V_1`
Hence, `T_2gtT_1` (ii) is O.K.
`DeltaW_(1rarr2)=+ve` (volume is increasing)
(iii) is O.K.
`DeltaQ=DeltaU+DeltaW,DeltaUgt0`
(iv) is wrong
