ΔU

[Rayna Irving 2C]

Under what circumstances does ΔU = 0?

[Brennan McGurrr 3C]

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

[Brianne Conway 1D]

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

[Valerie Tran 2B]

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

[Teti Omilana 1G]

In an isothermal reaction (when temperature is constant).

[Rachael Cohen 3G]

DeltaU is 0 in reversible reactions.

[Jeremy Wei 2C]

deltaU = 0 in isothermal reactions.

[Edgar Velazquez 2K]

It will be equal to zero in isothermal reactions where q=-w or w=-q.

[Fiona Huang 3C]

In isothermal, reversible reactions

[Kelly Ha 1K]

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