The first law of thermodynamics
What this topic asks you to be able to do
- recall W = p∆V for the work done when a gas expands or is compressed at constant pressure, and use it; understand how work done by the gas differs from work done on it
- recall the first law of thermodynamics, ∆U = q + W, and use it, where ∆U is the rise in internal energy, q is the heating of the system (the energy it gains by heating) and W is the work done on it
