Ice melts due to the chemical properties of water. There are more hydrogen bonds between the molecules of ice than in water.
Water boils when the thermal energy in the water, which is a type of kinetic energy which causes the water molecules to move around, exceeds the strength of the hydrogen bonds between the other molecules.
Answer:

Explanation:
The work (W) done by the gas can be calculated using the following equation:

<u>Where:</u>
p: is the pressure
[tex}V_{f}[/tex]: is the final volume
[tex}V_{i}[/tex]: is the initial volume
In the first process, the work done by the gas is:

Since the volume remains constant, the total work done by the gas is equal to zero.
In the second process, the work done by the gas is:
Now, the total work done by the gas during both processes is:

Therefore, the total work done by the gas during both processes is - 24 kJ.
I hope it helps you!
