## Homework Statement

One mole of an ideal gas initially at a temperature of T[tex]_{}i[/tex] = 4[tex]\circ[/tex] C undergoes an expansion at a constant pressue of 1.00 atm, to four times its original volume.

a.) Calculate the new temperature T[tex]_{}f[/tex] of the gas.

answer in K

b.) Calculate the work done on the gas during the expansion.

answer in Kj

## Homework Equations

P[tex]_{}f[/tex]V[tex]_{}f[/tex]/P[tex]_{}i[/tex]V[tex]_{}i[/tex] = nRT[tex]_{}f[/tex]/nRT[tex]_{}i[/tex]
