Answer #1

Heat that has to be supplied to increase the temparature from to is:

where, m is the mass in kg and C is the heat capacity of the iron metal.

Note: C can vary from 440 to 460 J/(kgK) depending on the iron metal purity. So, I assumed it with an average value of 450J/(kgK). In case, if the problem includes the C value, then that must be used as such.

The tempartures are given in and . So, one of them has to be converted to other units to match with same before to know the difference in temparature.

In order to rise the temperature by 80K i.e., to rise from 20C to 373K, one has to supply 18kJ heat energy to the iron pan.
