Question

In adiabatic process, the pressure is increased by 2/3%. If g = 3/2 then the volume decreases by nearly –

• A.
• B. $\frac { 2 } { 3 } \%$
• C. 1 %
• D. $\frac { 9 } { 4 } \%$

Answer 1

Answer: (A)

Answer 2

For adiabatic process

$\frac { \gamma \mathrm { P } } { \mathrm { V } }$

× 100 = –

$\frac { \Delta \mathrm { V } } { \mathrm { V } }$ × 100 = $\frac { 2 } { 3 }$

× 100 = × $\frac { 2 } { 3 }$

= × $\frac { 2 } { 3 }$ = $- \frac { 4 } { 9 }$ %
