In the statement ΔE = q + W. Why is ΔE regarded as a state functio

1.	In the statement ΔE = q + W. Why is ΔE regarded as a state function while q and W are individually not state functions?
Answer» ΔE is regarded as state function because it depends upon initial and final states of the system are not on the path e.g., CO₂obtained from various methods has some value of ΔE. Heat (g) and work (w) are not the state functions because they are path dependent.

Answer»

ΔE is regarded as state function because it depends upon initial and final states of the system are not on the path e.g., CO₂obtained from various methods has some value of ΔE.

Heat (g) and work (w) are not the state functions because they are path dependent.
