## delta U=0

isochoric/isometric: $\Delta V = 0$
isothermal: $\Delta T = 0$
isobaric: $\Delta P = 0$

### delta U=0

Why in an isothermal process is delta U always equal to zero?

Internal energy is dependent on temperature. In isothermal processes, temperature change is 0, thus internal energy change is also 0 for an ideal gas.
