Under which conditions does the molar volume of a gas decrease? O at 273 K and at 2.0 atm at 273 K and at 0.5 atm at 409.5 K and at 1.0 atm at 546 K and at 2.0 atm

THIS IS THE BEST ANSWER 👇

Under 273 K and under 2.0 atm conditions, the molar volume of the gas decreases

Step by step explanation:

Gas temperature and pressure depend on the amount of natural gas. The laws of volume with temperature and pressure are the laws of Charles and Boyle’s respectively.

Charles’ Law: The law requires that the amount of gas at intense pressure and moles be directly related to the temperature of the gas.

Mathematically,

V ∝ T (Constant pressure and number of moles)

The amount of gas also decreases and vice versa, as the temperature of the gas increases.

Boyle’s Law: The law requires that the pressure of a gas be proportional to the volume of the gas and the number of moles at constant temperature.

Mathematically,

P ∝ (At constant temperature and number of moles)

While volume is decreasing, gas pressure is rising and vice versa. Minimum and maximum pressure are required to reduce volume. The temperature will then decrease.

Hence, its 273 K and at 2.0 atm.
