Answer: "physical change" .
________________________________________________________
This would be a "physical change" . ________________________________________________________
<u>Note</u>: This would change from a "solid" to a "liquid" / mere rearrangement of molecules/ NOT a new chemical substance—hence, a "physical change".

3 km/h
formula for momentum = mass x velocity
It’s the 2nd one The reaction rates of the foward and reverse reactions are equal
The energy of the IR photon is
J. Thus, option C is correct.
The energy of the radiations propagating in the air with the velocity of
m/s is given by:

Where, <em>h </em>is Planck's constant, and
is the frequency.
<h3>Computation for the energy of IR photon</h3>
The value of Planck's constant is given as, 
The frequency of the IR radiation is 
Substitute the values for the energy of the photon

The energy of the IR photon is
J. Thus, option C is correct.
