Question

The volume of any gas at a pressure of 750 mm Hg at a temperature of 27⁰C is 1000 cm³. At what temperature will the volume of 700 mm Hg gas be 1400 cm³?​

Answer 1

Answer:

118.85°Celsius

Explanation:

P1=750; P2=700

V1=1000; V2=1400

T1=27=300 K; T2=?

By combined gas law,

[(P1V1)/T1]=[(P2V2)/T2]

[(750*1000)/300]=[(700*1400)/T2]

So,

T2=(980000*300)/750000=392 K=118.85°Celsius
