Question

At 250c and 760 mm of Hg pressure a gas occupies 600 ml volume. What will be the pressure at a height where temperature is 100c and volume of the gas 640 ml.​

Answer 1

Answer:

Correct option is A)

Given, P

1

=760mmHg, V

1

=600mL

T

1

=273+25=298K

P

2

=?

V

2

=640mL and T

2

=273+10=283K

According to combined gas law equation,

T

1

P

1

V

1

=

T

2

P

2

V

2

or P

2

=

V

=

(640mL)(298K)

(760mmHg)×(600mL)×(283K)

= 676.6mmHg
