Question

What is the pressure inside a balloon which is inflated in a single breath of 3.5 L. (radius of balloon = 9 cm).

Answer 1

Explanation:

Given What is the pressure inside a balloon which is inflated in a single breath of 3.5 L. (radius of balloon = 9 cm).

• We need to find the pressure inside the balloon.
• Given radius of balloon r = 9 cm = 0.09 m
• Force on the balloon f = 3.5 N
• So pressure p = force / area
• So area is given by A = πr^2
•                                     = 22/7 x 0.09 x 0.09
•                                      = 0.025 sq m
• Now pressure = F/A
•                       = 3.5 / 0.025
•                       = 3500 / 25
•                         = 140 N / m^2
• Therefore pressure inside the balloon will be 140 N / m^2
