Question

A gas at 80 kPa occupies a volume of 5 mL. What volume will the gas occupy at 70 kPa

Answer 1

Volume will the gas occupy at
`70` kPa
`= 5.71`

Step-by-step explanation:

As per the gas law

`P_1V_1 = P_2V_2`

Here

`P_1 =` initial pressure of the gas

`P_2` = final pressure of the gas

`V_1 =` Initial volume of the gas

`V_2` = the final volume of the gas

here,

`P_1 = 80` kPa

`V_1 = 5` mL

`P_2 = 70`

Substituting the given values in above equation, we get -

`80 * 5 = 70 * V_2\\V_2 = 5.71`

Volume will the gas occupy at
`70` kPa
`= 5.71`
