Question

A sample of gas has a pressure of 570 torr, temperature of -27 oC and volume of 500 mL. If the pressure is changed to 922 torr and the volume to 611 mL what is the new temperature in oC?

Answer 1

As number of moles remain constant;

$PV/T=constant$

Given:

$P_i=570torr;V_i=500mL;T_i=246K$

$P_f=922torr;V_f=611mL;T_f=?$

$\implies 570*500/246=922*611/T_f$

$\implies T_f= 486.253K=213.253°C$
