why does air pressure not squash our bodies?

because we have air inside our body too

what is the liquid state

500

the 3 factors that the mixing of diffusion depends on

1. temperature

2. size and mass of the particles

3. the states of the substances that are diffusing

500

definition of density

the mass of a substance in a certain volume

the amount of matter within a certain volume
