The heat flux, or the rate of heat transfer per unit area, is measured in watts (Watts) only A. TRUE B. FALSE
1 answer:
Answer: The given statement is false.
Explanation:
Heat flux is defined as the flow of heat or energy per unit time in per unit area. S.I. unit of heat flux is watts per square meter.
Heat flux is represented by the symbol .
So, it means heat flux is not measured in watts only as it includes per unit area also.
Therefore, we can conclude that the given statement heat flux, or the rate of heat transfer per unit area, is measured in watts (Watts) only, is false.

Answer:
The energy for 1 mole of these photons is E = 31 ×
Explanation:
Given data
Wavelength 639.8 ×
m
Plank constant h = 6.626 × J sec
Speed of light c = 3 × meter per second
We know that Energy of a photon is given by
Value of ( h c ) = 6.626 × × 3 ×
= 19.878 ×
639.8 ×
m
Now Energy of a photon
E = 0.031 × Joule per mole
E = 31 ×
Therefore the energy for 1 mole of these photons is E = 31 ×
