Question

What will happen at molecular level if two bodies one hot and one cool are brought in contact with each other?

• A. Molecules of hot object will become more active.
• B. Molecules of cold object will become lazier.
• C. Molecules of hot object will lose its activeness and cold object will gain some activeness.
• D. Nothing will happen, they will stay the same.

Answer 1

The correct option is C

Molecules of hot object will lose its activeness and cold object will gain some activeness.

If such objects are brought in contact with each other, then molecules of hot objects will lose its activeness that means they will become slower than before; whereas molecules of cold object will gain some energy and will become little active than before, ultimately they will equalize their level of activeness. And this will happen due to collision of the molecules of two objects.
