Re: ΔU
Delta U is zero in an isolated system because neither energy nor matter can be exchanged with the surroundings.

Re: ΔU
deltaU is 0 in an isothermal reversible expansion since the energy lost through work is replaced by heat from the surroundings, meaning q = -w.

Re: ΔU
In an isothermal reaction, delta U will be 0. You can also calculate q and w since delta U = q+w

Re: ΔU
ΔU = 0 in isothermal reactions and q= -w or -q= w since energy lost from work is replenished by heat.
