Question

A balloon holds 50.0 mL of nitrogen at 25° C and a pressure of 736 mm Hg. According to Boyle's Law, answer the following questions for 2 points each: What will be the effect on the pressure inside the balloon if the volume is decreased to 25 mL? Explain how this would demonstrate Boyle's Law. Explain Boyle's Law in terms of the kinetic energy of molecule

Answer 1

The correct answer is - would be double which is 1472 mm Hg.

Step-by-step explanation:

According to Boyle's law that says the relationship between volume and pressure of a gas at constant pressure shows an inverse relationship which means if volume will increase then pressure will be decrease and vice versa.

P1V1 = P2V2 .........Boyle's law

Given: P1 = 736 mm Hg

V1 = 50 mL

P2 = ?

V2 = 25 mL

Solution:

from the Boyle's law

(P1V1)/V2 = P2

736×50/25 = P2

P2 = 1472

So the decreasing the volume to half increases the pressure double. It proves it follows Boyle's law
