If the burning of the fuel in a potato cannon performs 855 J of work on the potato and produces 1422 J of heat, what is #DeltaE# for the burning of the fuel?

DeltaE = Q - W Where: DeltaE = change in internal energy Q = heat added to the system W = work done by the system
Given: Q = 1422 J (heat produced) W = 855 J (work done on the potato)
DeltaE = 1422 J - 855 J DeltaE = 567 J
Therefore, the change in internal energy for the burning of the fuel is 567 J.

The change in internal energy (ΔE) for the burning of the fuel can be calculated using the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system:
ΔE = Q - W
Where: ΔE = change in internal energy Q = heat added to the system W = work done by the system
Given: Q = 1422 J (heat produced) W = 855 J (work done on the potato)
Plugging in the values:
ΔE = 1422 J - 855 J ΔE = 567 J
Therefore, the change in internal energy (ΔE) for the burning of the fuel is 567 Joules.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
