Answer 2

We should not open the door open the door is hot because our hand can be burnt.

- Door knobs are mainly made out of metal.

- Metals have extremely high retaining capabilities of the heat energy.

- So if a metal piece is hot,there are obvious possibilities that the metal piece is retaining a high amount of heat energy.

- This high amount of heat energy can easily burn us because our skin is very sensitive.
