Question

What temperature would be necessary to double the volume of a gas, initially at S.T.P., If the pressure is decreased to 50%

Answer 1

=273 K =?

=1 ATMOS. PRESSURE ATMOS. PRESSURE

=V =2 V

T2 = 273 Kelvin

or T2 = 0°Celsius

Note: Hence, the temperature is constant and vary the Pressure and volume, it is nothing but Boyles gas law.
