Chapter 7, Problem 7.101QP

Interpretation Introduction

Interpretation:

The number of photons are needed to increase the temperature of water by ${\text{5}}^{\text{o}}\text{C}$ has to be calculated.

Concept introduction:

The energy of each photon is given as

$\text{E}\text{=}\text{hν}$

Where,

h is Planck’s constant ($\text{6}\text{.63}\text{×}{\text{10}}^{\text{-34}}\text{J}\text{.s}$ ) which relates energy and frequency.

$\text{ν}$ is the frequency.

E is energy of light particle.
