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

Under  273 K and at 2.0 atm conditions the molar volume of a gas decrease

Step-by-step explanation:

Temperature and gas pressure depends on the volume of a natural gas. Charles's law and Boyle's law respectively are the laws relating to volume with temperature and pressure.

Charles' Law: The law dictates that the amount of gas at intense pressure and moles is directly related to gas temperatures.

Mathematically,

V ∝ T    (At constant pressure and number of moles)

The volume of the gas also decreases and vice versa, with the gas temperature increasing.

Boyle's Law: The law dictates that the pressure of the gas becomes inversely proportional to the gas volume and the number of moles at constant temperature.

Mathematically,

P ∝    (At constant temperature and number of moles)

Although the volume declining, gas pressure is rising and vice versa. There must be a minimum and a maximum pressure to reduce the volume. The temperature will then decrease.

Hence, its 273 K and at 2.0 atm.

answer: slight chance that it will happen
