Question 21

Heat

Answer 21

Heat causes particles to move, vibrate on the spot or travel about
* All objects have some heat so all particles are moving all the time
* Giving an object more heat, makes the particles move faster.

Question 22

Expansion

Answer 22

Heating a substance causes it to expand. This is because when the particles move faster, they are also able toove more further away from each other

Question 23

Gas pressure

Answer 23

The combined force between the huge numbe of gas particles colliding with and bouncing on the surfaces

Question 24

If the gas pressure outside of and object is bigger than the glass pressure inside of an object, the difference can be so powerful enough to crush an object

Answer 24

Fact!

Question 25

Diffusion

Answer 25

The random motion of liquid and gas particles where they spread out and become less concentrated.
Diffusion happens faster if the substances are hotter, because the particles are travelling faster.
