You have a piece of aluminium whose mass is 800 g, and suppose it is heated up to 1000∘C.
Now, given that you are cooling it down to 150∘C, calculate the amount of heat (in Joules) given out during the process of cooling.
Details and assumptions:
- The specific heat capacity of aluminium is CAluminum=900 J/kg K.
- Ignore the heat energy lost to the atmosphere.
