Heat energy

The video tutorial explains the process of shaping metal in a foundry. It describes how metal is melted into a liquid state by transferring heat energy from a hot fire to the cooler metal, causing the metal molecules to vibrate faster. As the metal heats up, it becomes bendy and eventually melts, allowing it to be poured into moulds. Once in the mould, the metal cools, transferring energy to the surrounding air, and solidifies into the shape of the mould. This process demonstrates how heat energy can change the shape of metal.

Explain how molten metal is formed and what happens to it after pouring into a mold.

How does the cooling process affect the state of molten metal?
