Question

4. . A gas occupies a volume of 40.0 dm' at standard temperature (0°C) and pressure (1 atm), when pressure is increases up to 3 atm unchanged temperature what would be the new volume? of 750 ​

Answer 1

Correct option is C)

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

745×250

=931.25 mm Hg

Additional pressure required =931.25−745=186.25 mm
