Which mechanism describes a Roman siege tower’s (Helepolis) vulnerability to fire?

💡 Explanation

Enhanced convective heat transfer causes rapid temperature rise in the tower's wood because fire provides a large temperature gradient that accelerates heat transfer, therefore increasing fire risk rather than preventing it. The tower ignites because hot gases flow around supports, facilitating rapid heating.
