The conditions of temperature and pressure in which a gas least soluble in water is low pressure and high temperature.
<h3>What is Henry Law?</h3>
The amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid, according to Henry's law.
From this law it is clear that:
- As the pressure of the gas increases solubility of the gas on the liquid also increases.
But if the temperature of the liquid decreases then the solubility of the gas also increases.
Hence at low pressure and high temperature, gas is least soluble.

<h2>Answer:</h2>
He is right that the energy of vaporization of 47 g of water s 106222 j.
<h3>Explanation:</h3>
Enthalpy of vaporization or heat of vaporization is the amount of energy which is used to transform one mole of liquid into gas.
In case of water it is 40.65 KJ/mol. And 18 g of water is equal to one mole.
It means for vaporizing 18 g, 40.65 kJ energy is needed.
So for energy 47 g of water = 47/18 * 40.65 = 106.1 KJ
Hence the student is right about the energy of vaporization of 47 g of water.
I believe the compound is Phosphorus pentoxide
