<span>From the poem Unlucky Boat by George Mackay
Brown, the line "bunged to the eyes with rust and penicillin" means

starting to live on it for the longest period it remains stagnant and starts decaying.</span>
The height of the water represents temperature whereas the flow of water represents the heat flow. Heat always flows from a higher temperature to a lower temperature.
