Answer:

please make me brainliest

Explanation:

air expand on heating :Place the bottle in a container filled with boiling water. After some time you will notice that the balloon gets inflated. this happens because of the air inside the bottle expands on heating and it fills the balloon. Take out the bottle out of the container and allow it to cool itself.

conduction of heat:

Boil some water in a kettle and pour it into a coffee mug. Put all four spoons into the water at once, arrange them so they aren't touching, and then feel the difference in temperature in each spoon. The spoons will be soaking up the heat from the water and the more conductive the material, the hotter it will feel.
