How to express the heat capacity in terms of heat?
The first law of thermodynamics divides the internal energy change into contributions of heat and work.
$$\text dU=\omega_Q-\omega_W,$$
Here I chose the notation to emphasise that the two parts are ...

Heat Flux and Spatial Temperature Gradients
The derivation for Heat Equation I am reading starts by stating
Net change of heat inside $[x,x+\Delta x]$ = Net flux of heat across boundaries + Total heat generated inside $[x,x+\Delta x]$ and ...
