# A container of carbon dioxide gas at a pressure of 325 kPa and a temperature of -5.20°C has a fixed volume. What is the pressure inside the container after it warms to 22.5°C?

Gay Lusaac's Law holds that $P \propto T$.............

#### Explanation:

Gay Lusaac's Law holds that $P \propto T$, for a given quantity of gas, a fixed volume, and absolute temperature.

And thus, ${P}_{1} / {T}_{1} = {P}_{2} / {T}_{2}$

We want ${P}_{2} = {P}_{1} / {T}_{1} \times {T}_{2}$, which expression clearly has units of pressure, as required (why?).

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