Question

At s.t.p,a certain Mass of gas occupies a volume of 800cm3. Find the temperature at which the gas occupies 1000cm3 and has a pressure of 720mmhg

Answer 1

At S.T.P

Pressure = 760mmHg

Temperature = 273

$\frac{P_1V_1}{T_1}= \frac{P_2V_2}{T_2}$

$T_2=$ $\frac{P_2V_2T_1}{P_1V_1}$

$T_2=\frac{720×1000×273}{760×800}=323.29K$
