How many number of moles of photon would contain sufficient energy to raise the temperature of 225 g of water from 21oC to 96oC? The specific heat of water is 4.18 Jg−1K−1 and the frequency of light radiation used is 2.45×109 s−1.[Given: Energy required to raise the temperature = mass x specific heat x ΔT]

How many number of moles of photon would contain sufficient energy to raise the temperature of 225 g of water from 21oC to 96oC?

The specific heat of water is 4.18 Jg1K1 and the frequency of light radiation used is 2.45×109 s1.

[Given: Energy required to raise the temperature = mass x specific heat x ΔT]
