Homework Help: Chem

Does my work here look right?

3. One mole of an ideal gas expands adiabatically into a vacuum. Calculate q, delta-e, w, and delta-H for the process.

q= 0 [adiabatic]

w= -Pext(V2-V1)
w= 0

delta-e = w + q
delta-e = 0 + 0 = 0

delta-h= delta-e + P(delta V)
delta-h= 0 + 0 = 0

does this seem right? The problem doesn't give me any information besides the fact that it's adiabatic, a vacuum, and there's one mole of a gas, so I didn't know the volumes or temperature- that's the only thing that's making me believe that everything is 0.
