Multiple Choice

Solve.
-The volume $\mathrm { V }$ of a gas varies inversely as the pressure $P$ on it. The volume of a gas is $260 \mathrm {~cm} ^ { 3 }$ under a pressure of $20 \mathrm {~kg} / \mathrm { cm } ^ { 2 }$ . What will be its volume under a pressure of $40 \mathrm {~kg} / \mathrm { cm } ^ { 2 }$ ?

A) $130 \mathrm {~cm} ^ { 3 }$
B) $494 \mathrm {~cm} ^ { 3 }$
C) $520 \mathrm {~cm} ^ { 3 }$
D) $137 \mathrm {~cm} ^ { 3 }$
