Question

Now assume that the water is contained in a 0.1-kg aluminum pot (cAl = 900 J/kg-K) that is initially at 293 K just like the water. How much energy must be transferred into the pot-and-water system in order to raise its temperature to the boiling point of water?

Answer 1

The energy transferred into the pot and water system in  order to raise its temperature to the boiling point of water is Q = 7213.5 J.

Explanation:

The thermal energy is transferred from one object to another with a  temperature difference is called heat and it is measured in joules (J). This is because heat is a transfer of energy.

The energy moves from the hotter object to the colder object during the energy transfer whereas the hotter object gets cooled and the colder object gets warmed up.  

(The boiling point of water is 373.15 K)

The energy transferred is given by the formula,

Q = mass of Pot * Specific Heat of Aluminum * ( 373.15 - 293 )

Q = 0.1 * 900 * 80.15

Q = 7213.5 J
