gas at a constant mass and pressure. According to this law, what would
happen to the volume of the gas if its temperature decreased from 400 K to
300 K?
O

Answer 1

A si the answer i just did the test

Answer 2

Option B. The volume would be 3/4 of its original value.

Step-by-step explanation:

T1 = 400K

T2 = 300

V1 = V

V2 =?

V1 /T1 = V2 /T2

V/400 = V2 /300

Cross multiply to express in linear form

400 x V2 = 300 x V

Divide both side by 400

V2 = 300V/400

V2 = (3/4)V

Therefore, the new volume will be 3/4 of the original volume.
