What occurs to the cannon tube and breech during firing?

During the firing of a cannon, the tube and breech are subjected to extremely high temperatures due to the combustion of gunpowder and the rapid expansion of gases produced during the firing process. The intense heat generated can significantly raise the temperature of these components, which can affect their material properties and performance. High temperatures are expected in a firing scenario, as the firing process generates significant thermal energy that is transmitted to the metal surfaces, resulting in a very hot cannon tube and breech after multiple firings.

This increase in temperature is a critical factor to consider for the safe and effective operation of artillery systems, as excessive heat can lead to wear, potential malfunction, or damage if not managed properly. Other processes related to maintenance or cooling are secondary to the immediate effect of temperature increase during the act of firing.
