Question

what will be the volume of a gas when 3 litres of it is cooled down from 15 degree Celsius to -73 degree Celsius at constant temperature.

Answer 1

your question is wrong.

correct question is,

What will be the volume of a gas when 3 litres of it is cooled down from 15 degree Celsius to -73 degree Celsius at PRESSURE.

here's the answer,

Temperature should be in Kelvin

so, T1 = 273+15=288

T2= 273+(-73)=200

At constant pressure,

V1T2=V2T1

so V2= V1*T2/T1

hence,

3*200/288

=2.08L
