A closed container contains an ideal gas. Which of the following changes will result in a decrease in temperature?
Correct answer: A. Volume = decrease temperature = decrease
- A. Volume = decrease temperature = decrease
- B. Volume = decrease temperature = increase
- C. Volume = increase temperature =decrease
- D. Volume = increase temperature = increase
Explanation
Option: A As volume and temperature are directly proportional to each other, so, by decreasing volume, temperature will also decrease. V ∝ TThe remaining options are incorrect according to the relation of V and T. Option B : V ∝ T So, when volume decreases, the temperature will not increase.Option C : When volume increases, the temperature will not decrease.Option D : Volume increase and temperature increase will not result in a temperate decrease.

About Ideal Gas Equation
The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.
