Question

the energy required to melt 1 gram ice is 33 June the number of kind of radiation frequency 4.67 into 10 to the power 13 second that must be absorbed to melt 10 gram ice is

Answer 1

Hello Dear,

There are lot of mistakes in your question.

# Correct question is -

Q. The energy required to melt 1 gram ice is 33 J. The number of quanta of radiation frequency 4.67×10^13 Hz that must be absorbed to melt 10 gram ice is -

◆ Answer -

N = 1.065×10^22 quanta

● Explaintion -

# Given -

ν = 4.67×10^13 Hz

# Explaination -

Energy required to melt 10 g ice will be -

E = 10 × 33

E = 330 J

Energy in one quanta is given by -

Φ = hν

Φ = 6.63×10^-34 × 4.67×10^13

Φ = 3.1×10^-20 J

No of quanta of energy absorbed by ice -

N = E / Φ

N = 330 / 3.1×10^-20

N = 1.065×10^22 quanta

Hope this is helpful. Keep asking..
