1

what is the equation for density?

density= mass(kg) / volume (m^3)

2

what can float in water?

objects' that density is less then the volume of water

3

what can increase internal energy?

the temperature increasing

4

latent heat energy is....

... the energy needed for the substance to change state without changing the temprature

5

the equation for energy is....

... energy= mass * length

6

why does a balloon keep it's shape?

Because of the pressure created between the collisions inside

7

if you have double the pressure there is...

... double the volume

8

Specific latent heat=

Energy / mass

9

The freezing point of a substance is the same as it’s...

Crystallisation point

10

What is gas pressure caused by?

The molecules hitting the walls
