If the the level of water in a container is compared before and after the fusion, it can be realized that the ice has a higher level than that of liquid water: solid and liquid water does not have the same volume.
We can generalize:
A state change always causes a change in volume.
Comment:
Water is an exception, volume increases during a melting for most of substances.

When 1 mole of carbon is burned, carbon dioxide is produced, and 393 kilojoules (kJ) of energy are released. If this reaction is

EleoNora [17]

The energy of 393 kJ is released as heat. Then, the container will experience an increase of temperature and, given that it is sealed, also an increase of pressure.

The increase of temperature results from the heat developed during the reaction.

The increase of pressure results from the fact that that the solid carbon will become gaseuos carbon dioxide. This gas will occupy a larger volume than the solid carbon and also this elevation of the temperature will make the pressure of the gas inside the container increase.
