In: Chemistry

What volume of air will be expelled from a vessel containing 400 cm3 at 7°C when it is heated to 27° C at the same pressure ?

we have to solve this question using gas laws.

Expert Solution

I have used the Charles law, which is one of the gas laws and relates volume to the temperature of the gas.

 

we have 

Initial Volume:(Vi)=400 cm³

Initial Temperature:(Ti)=7°C = 273 +7 = 280K

Final Temperature:(Tf)=27°C = 300K 

we have to find the 

Final Volume: (Vf)=?

 

V1/T1=V2/T2

Vi/Ti=Vf/Tf

400/280=Vf/300

Vf=400*300/280

Vf=428.5

 

We need the volume of air expanded so

Vf-Vi=428.5-400

        =28.5cm³


=28.5cm³
