When a substance is heated the particles do what?
accelerate
What is happening to the molecules of a substance when they are heated or cooled?
move faster when heated they move slower when cooled
What two things happen to particles in a substance when the substance is heated?
molecular break down and gasification.
Are the particles in a solid linked?
Yes, they have tiny bonds that when the substance is heated break and the substance forms a liquid.
What does the particle theory suggest about the motion of the particles of solids-liquids and gases when they are heated?
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
What does the particle theory suggest about the motion of the particles of solids liquids and gases when they are heated?
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
When substance is heated its particles expand and increase in size?
it expands and it becomes bigger
When a substance is heated its temperature increases. What happens to the energy of its particles?
The energy of its particles increases, so as the particles speed up move faster causing its heating up.
What happens to particles in a substance when its heated or cooled?
In a solid, the particles start to vibrate a lot.In a liquid, the particles begin to move around faster and faster.In a gas, the particles move extremely fast through the air.
How do particles move when they are heated?
Particles move faster when they are heated.
What process is happening at boiling point?
The intermolecular bonds between particles in a substance are breaking, causing them to fly around.
What type of substance is heated by radiation?
Any substance that absorbs the radiation is heated by it.
