Question

A gas with constant temperature has a pressure of 123 kPa and a volume of 123.13 L. A pressure change caused the volume to decrease to 28.15 L. Based on the relationship between pressure and volume, what must have happened to the pressure?



A
Pressure decreased.

B
Pressure increased.

C
Pressure stayed the same.

Answer 1

Answer:

The answer to your question is: Pressure increased

Explanation:

Data

P1 = 123 kPa

V1 = 123.12 l

V2 = 28.15 l

P2 = ?

Formula

                          P1V1 = P2V2

                         P2 = P1V1/V2

Process

                        P2 = (123)(123.12) / 28.15

                        P2 = 537.97 kPa

Pressure increased
