A sample of fluorine gas with volume 410 ml at 25 C is heated to 198 C with the pressure remaining constant.
The volume (V) of n moles of a substance in the gaseous state, at temperature T and under pressure P is given by `V = (n*R*T)/P` where R is a constant equal to 8.314 J/(mol*K)
Here, n, R and P are constant; only T varies and increases from 298.15 K to 471.15 K.
The volume increases from 410 ml to `410*(471.15/289.15)` = 647.9 ml
The final volume of the sample of fluorine at 198 C is 647.9 ml
