Find the number of photons of radiation ...

Find the number of photons of radiation of frequancy `5xx10^(13)s^(-1)` that must be absorbed in order to melt one g ice when the latent heat of fusion of ice is `330J//s`.

Text Solution

Verified by Experts

The correct Answer is:
`10^(22)`
`330J=n(hv)`
`330J=n[6.62xx10^(-34)xx5xx10^(13)]`
` (330)/(6.62xx10^(34)xx5xx10^(13))=n" "10^(22)=n`
