Question

A 0.5-L container of nitrogen gas is heated under constant pressure to the boiling point of water. What is its new volume?

Answer 1

So clearly, the dinitrogen gas is in a piston......

Explanation:

And according to old Charles' Law, `V_1/T_1=V_2/T_2`

We ASSUME that `T_1=298*K` (i.e. room temperature), and it is a given that `T_2=373*K`...........

`V_2=V_1/T_1xxT_2=(0.5*L)/(298*K)xx373*K=626*mL......`
