When matter is heated does it move fast or slow?
When matter is heated the molecules in it move faster.
What happens to the pressure of gas when it is heated and why?
The molecules of a gas move faster when heated so the pressure increases.
What does a balloon do when heated?
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
Is pressure higher or slower when molecules move faster or slower?
Molecules move more rapidly when heated as their kinetic energy is increased so their speed increases.
Why does an iron wire expand when heated?
That's not just an iron wire - most materials expand when heated. This is called thermal expansion, and has to do with the fact that molecules move faster when it is hotter.
When molecules in liquids and gases are heated they?

Why do molecules move faster when heated?
Because of friction
Do molecules move faster when a solid is heated?
yes
What happens to a fluid when it heats?
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.

What happens to the molecules of air when they are heated?
they get exited and move faster than cold molecules
What is happening to the molecules of a substance when they are heated or cooled?
move faster when heated they move slower when cooled
Why metal expands when heated?
Molecules move back and forth faster and faster causing expansion
What happens to the pressure of gas when it is heated and why?
The molecules of a gas move faster when heated so the pressure increases.
How does the speed of the molecules of a gas change when the ga is heated?
it moves faster
How does the movement of molecules inside a solid block of iron change as the iron is heated?
The molecules move faster
What happens to the density of a fluid when it is heated?
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.
