<span>Evaporation
is a type of vaporization of a liquid that occurs from the surface of a
liquid into a gaseous phase that is not saturated with the evaporating
substance. The other type of vaporization is boiling, which is
characterized by bubbles of saturated vapor forming in the liquid phase.</span>
Answer: 1.311 × 10^18 photons are produced in each pulse
Explanation: Please see the attachments below
ice because it can melt back to water
Answer:
C. 26.4 kJ/mol
Explanation:
The Chen's rule for the calculation of heat of vaporization is shown below:
Where,
is the Heat of vaoprization (J/mol)
is the normal boiling point of the gas (K)
is the Critical temperature of the gas (K)
is the Critical pressure of the gas (bar)
R is the gas constant (8.314 J/Kmol)
For diethyl ether:
Applying the above equation to find heat of vaporization as:
The conversion of J into kJ is shown below:
1 J = 10⁻³ kJ
Thus,
<u>Option C is correct</u>
