When 5.00 mol of benzene is vaporized at a constant pressure of 1.00 atm and at its normal boiling point of 80.1°C, 169.5 kJ are
absorbed and PΔV for the vaporization process is equal to 14.5 kJ.
What is the change of internal energy?
What is the change of enthalpy?
Is the change in entropy positive or negative for this process?
If the pressure would be only ½ atm, what are the changes of internal energy and enthalpy during vaporization (approximately)?
How much energy is absorbed?
Write the definition of the Gibbs Free Energy.
At the lower pressure, will the boiling point be higher or lower.

The properties like shape, structure, etc. that define the appearance of matter is said to be its physical properties whereas the properties like oxidation, toxicity, etc. that defines how a new product is formed from the other substances is said to be its chemical properties.
It is given that a 2.0 L volume of hydrogen gas is combined with 1.0 L of oxygen gas to produce 2.0 L of water vapor. The chemical reaction is as:
Since, the reaction between hydrogen and oxygen results in the formation of complete new product, water. So, oxygen will undergo a chemical change.
