1. The problem statement, all variables and given/known data
One mole of an ideal gas initially at a temperature of T$$_{}i$$ = 4$$\circ$$ C undergoes an expansion at a constant pressue of 1.00 atm, to four times its original volume.

a.) Calculate the new temperature T$$_{}f$$ of the gas.
answer in K
b.) Calculate the work done on the gas during the expansion.
answer in Kj

2. Relevant equations

P$$_{}f$$V$$_{}f$$/P$$_{}i$$V$$_{}i$$ = nRT$$_{}f$$/nRT$$_{}i$$

Well you have the ideal gas equation, as you have already pointed out. What do you think we could do with it?
