Heating 235g of water from 22.6 C to 94.4 C in a microwave requires 7.06 X 10^4 J.  If the microwave frequency is 2.88X10^10/s, how many electromagnetic quanta are required to supply the required 7.06 X10^4 Joules?

Planck's relation is the formula which links the energy in Joules(E) of a photon with its frequency in Hertz (v) through Planck's Constant(`h=6.626*10^-34 J*S` ).


As a photon is a quantum of electromagnetic energy, we can calculate the energy...
