The temperature of a 3.00 L sample of gas is lowered from 353 K to 303 K. What will be the resulting volume of this gas?
As far as we know it would remain at
You haven't proposed this question properly; the volume of a gas is a state function of pressure, temperature, and amount of gas.
The problem should read.........
We don't know the boundary conditions of the problem, and are forced to make assumptions.
