One mole of a monatomic gas at 433 K is reversibly taken to half of its original volume by an isobaric process. How much work is done by the gas

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
