Answer:

Gay Lusaac's Law holds that #PpropT#.............

Explanation:

Gay Lusaac's Law holds that #PpropT#, for a given quantity of gas, a fixed volume, and absolute temperature.

And thus, #P_1/T_1=P_2/T_2#

We want #P_2=P_1/T_1xxT_2#, which expression clearly has units of pressure, as required (why?).

#P_2=(325*kPa)/(267.9*K)xx295.7*K=??kPa#
