Q. The volume of a gas is 1092 cc at STP. Find the volume of the gas at a temperature of 180°C and a pressure of 76 cm Hg.
Solution:
Given:
Since pressure remains constant (P1 = P2), we apply **Charles's Law**:
V1 / T1 = V2 / T2
Substituting values:
1092 / 273 = V2 / 453
V2 = (1092 × 453) / 273 = 1812 cc
The volume of the gas at 180°C and 76 cm Hg is 1812 cc.
