Behavior of Gases

Question 13 • CCPS-2002400-Integrated Science 1 SEM A (IC) SY27

A gas has an initial volume of 212 cm3 at a temperature of 293 K and a pressure of 0.98 atm. What is the final pressure of the gas if the volume decreases to 196 cm3 and the temperature of the gas increases to 308 K?

Answer
A
0.86 atm
B
0.95 atm
C
1.0 atm
D
1.1 atm

Explanation

Use the combined gas law: P₁V₁/T₁ = P₂V₂/T₂. Solving gives P₂ = (0.98 atm × 212 cm³ × 308 K)/(293 K × 196 cm³) ≈ 1.12 atm, which rounds to 1.1 atm. The correct choice is D, 1.1 atm.
