Question

a gas occupies a volume of 200ml of 17°c and 700mm pressure.what volume it occupie at 47°c and 60mm pressure?​

Answer 1

Answer:Given: P  

1

​  

=745 mm Hg

V  

1

​  

=250 ml  

V  

2

​  

=200 ml

∴ By Boyle's law as the temperature is constant.

P  

2

​  

=  

V

P  

1

​  

V  

1

​  

 

​  

=  

200

745×250

​  

=931.25 mm Hg

Additional pressure required =931.25−745=186.25 mm
