Concepts Of Physics MCQ Edition [Volume 2]PhysicsKinetic Theory of Gases
A gas cylinder features walls capable of withstanding a maximum pressure of 1.0 10^6 Pa . Inside, it holds a gas at 8.0 10^5 Pa and 300 K . The cylinder is heated steadily. Assuming no change in volume, determine the temperature at which the cylinder will break.
Options
- A325 K
- B375 K
- C240 K
- D450 K
Correct answer
B. 375 K
Step-by-step solution
Given initial pressure P₁ = 8.0 10^5 Pa and initial temperature T₁ = 300 K . The maximum pressure the cylinder can withstand is P₂ = 1.0 10^6 Pa . Since the volume of the cylinder remains constant, Gay-Lussac's law is applicable: P₁ T₁ = P₂ T₂ Substituting the given values: 8.0 10^5 300 = 1.0 10^6 T₂ T₂ = 1.0 10^6 300 8.0 10^5 T₂ = 10 8 300 T₂ = 375 K
