The question is so simple but complicate .
As you know that when liquid is heat it turns to liquid but question is that what happened inside?
When temperature raised the liquid began to boil as a result the liquid particles moves randomly or vibrate and collides each other and produce internal energy when temperature reaches in a certain limit it will turn into gas form so gas will moves upward to the atmosphere and evaporate.
I hope you will understand better now so click below and tell me how was ans.
