Question

Which of the following samples of gas would have a new volume of 3.00 liters if the pressure is decreased from 3.00 atm to 1.00 atm at constant temperature?

Answer 1

The group of choices associated with the questions is as follows:

A) 1.00 L He

B) 5.00 L CO2

C) 9.00 L H2S

D) more than one correct response

E) no correct response

Answer:

The correct answer is - A) 1.00 L He

Explanation:

According to the Boyles law, the pressure of the gas is inversely proportional to the volume of the gas at a constant temperature which means if the pressure increases then the volume will decrease and vice versa.

The equation of Boyle's law :

P1V1=P2V2

and V1 = P2V2/P1

Placing the value

V1 = 3*1/3

V1 = 1 L

thus, there is only one option has one liter that is A) 1.00 L He
