Question

1. Name the 4 variables that define any gas.

2. If the temperature and # of moles are constant, what happens to to the volume when the pressure increases.

3. Use this effect to explain how we breathe.

4. If the pressure and moles are constant, what happens to the volume when the temperature increases?

Answer 1

1)

The 4 variables that define gas are:

---> Pressure

---> Temperature

---> Volume

---> Density

2)

Here moles are directly proportional to volume . As moles increases volume increases .

Therefore, the volume will increase
