Question

A 920-g empty iron kettle is put on a hot stove. How much heat must the kettle absorb to raise its temperature from to The specific heat capacity of iron is ?

Answer 1

The units of Cp (Specific Heat) set up the problem for you.

Cp (Iron) = 113c/kgC × 4.184J/c = .4728kJ/kgC

Cp (Iron .4728kJ/kgC) × .920kg × (93.0C-15.0C) = 33.928kJ
