Why do gases expand faster than liquids when heated?
Heat causes the molecules to move faster, (heat energy. is converted to kinetic energy) which means that the volume of a gas increases more than the volume of a solid or liquid.
Why does liquid turn into a gas when heated?
If you heat a liquid like water up even more (like if you put it in a pot on the stove), then the molecules will move around so fast that they can’t even hold on to each other at all. When this happens, all of the molecules go flying apart and become a gas (like when you boil water to make steam).
What happens to the density of liquids when they are heated?
The density of a liquid that is heated decreases. When a substance is heated, the molecules and atoms in the substance speed up and move faster, causing the space between the molecules and atoms to increase. So, when a liquid is heated, the atoms in the liquid move faster and spread further apart; therefore, the density decreases.
Do all substances expand when heated?
Solids, liquids and gases all expand when heat is added. When heat leaves all substances, the molecules vibrate slower. The atoms can get closer which results in the matter contracting. Again, the mass is not changed.
