Topic - Physics question about defrosting meat

andy_e on 23 Dec 2013
If I have a 3.5kg shoulder of pork wih a specific heat capacity of 2.1kJ/kgK. If it was in a freezer at -15celsius and then left at room temperature at 15degrees, how long should it take till it warms up to room tenperature?

So far I have figured it needs 220kJ of energy input to warm up, but I'm stuck at a heating rate. Presumably this is related to the temperature difference of the meat and the room, and the rate decreases in some linear (or at least predictable) fashion as the two temperatures converge.

Any one with a better memory of physics able to help?
