Question

You have 50 L of CO2 gas at standard temperature and pressure (STP). What would need to be done to the pressure to cut the volume of gas in half?

Answer 1

we have to double the pressure.

Step-by-step explanation:

b/c according to boyle's" the volume of a given mass of gas is inversely proportional to its pressure in a constant temperature.

P1*V1=P2*V2

we have P1=1 atm because it is at STp

V1=50L

V2=25L because we want to cut the volume of the gas in half .

and we can find P2

from the above formula we have P2=P1*V1/V2

P2=1*50/25=50/25=2

so when we doubled the pressure the volume will be halved.
