Question
In a process the pressure of a gas is inversely proportional to the square of the volume. If temperature of the gas increases, then work done by the gas:
Options
A.is positive
B.is negative
C.is zero
D.may be positive
Solution
P α 
⇒ P = 
⇒ PV2 k
⇒ PV. V = k ⇒ nRTV = k ⇒ TV = k1
Since temperature increases therefore volume decreases or work done by the gas is negative.
⇒ P = ⇒ PV2 k⇒ PV. V = k ⇒ nRTV = k ⇒ TV = k1
Since temperature increases therefore volume decreases or work done by the gas is negative.
