Question

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?

Answer 1

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`
