Answer 2

Answer:

1.065 * 10^22

Explanation:

Energy required to melt 1g ice =33J.

Energy required to melt 10g ice =33×10=330J.

Radiation frequency (ν)=4.67×10 ^13 s^−1

As we know, the energy of radiation is given by:

E=hν

Here, h= Planck's constant =6.62×10^−34J.s

∴E=6.62×10 ^−34 × 4.67×10 ^13

⇒E=3.09×10 ^−20 J

∴ No. of quanta required =

3.09×10 ^−20/330

​

=1.067×10 ^22
