A sample of nitrogen gas was transferred to a 100 mL container at 100 kPa and 75.0 C. What was the original temperature of the gas if it occupied 125 mL and exerted a pressure of 125 kPa?

Well, what does the #"combined gas equation"# hold....?

...that #(P_1V_1)/T_1=(P_2V_2)/T_2#

...and this insists units of #"absolute temperature..."#

We solve for #T_1-=(P_1V_1)/(P_2V_2)xxT_2#

#=(125*kPaxx125*mL)/(100*kPaxx100*mL)xx348.15*K-=544.0*K#
