One mole of an ideal gas (CP = 5R/2) in a closed piston/cylinder is compressed
from Ti = 298 K, Pi = 0.1 MPa to Pf = 0.25 MPa by the following pathways. For each
pathway, calculate ΔU, ΔH, Q, and WEC: (a) isothermal; (b) constant volume; (c)
adiabatic.

i need your help as soon as possible please!!!
please give me step by step so i can understand it
Thank you!

The answer is as follow-

1) Isothermal -> w= -q , dH=dU=0

2) const. Volume -> w=0, dU=q=ncvvdT, dH=ncppdT

3) Adiabatic -> q=0, dU=ncvdT
