What happens to gas molecules when they are heated?
Answers
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. Solids, liquids and gases all expand when heat is added.
Answer:
Kinetic energy increases.
Explanation:
When we heat gas molecules, their vibration on their mean position increases and because of it, their energy increases. And when they get more energy, they start colliding with each other at greater speed.
And if these molecules can react with each other then they will get a sufficient energy which is called threshold energy to start the reaction. And thus reaction takes place.
But if the molecules are of same kind i.e, only of oxygen or hydrogen or if they can't react. Then there will be no reaction.
