Question 1 If the enthalpy of a system increases, what value of ΔH describes the process? ΔH is positive. ΔH is negative. ΔH is zero ΔH increases.

If ΔH is positive, it means the process is endothermic. That it means it collects heat from the surroundings.

If ΔH is negative, it means the process is exothermic. That it means it gives out heat to the surroundings.

Sorry don't have the answer to the last part.
