Answer 1

Answer:

Explanation: Most materials when heated will expand (water being one exception when its temperature is close to zero degrees celcius). If various metals are heated in a bunsen flame then they will expand. ... If a metal plate containing a hole is heated then the whole plate will expand including the hole.
