Question

A balloon is inflated with helium gas at room temperature of 25c and at 1 bar pressure when its initial volume is 2.27l and allowed to rise in the air. As it rises in the air external pressure decreases and volume of the gas increases till finally it bursts when external pressure is 0.3 bar. What is the limit to which volume of the balloon can be inflated

Answer 1

Answer:

it is talkinb about stp i think

Explanation:

u can use ideal gas equation feom thermo dynamics

PV=nRT

Hey Dear,

◆ Answer -

Max volume = 7.567 L

◆ Explaination -

# Given -

T = 25 ℃ = 298 K

P1 = 1 bar

V1 = 2.27 L

P2 = 0.3 bar

# Solution -

Applying Boyle's law to rising balloon,

P1.V1 = P2.V2

V2 = P1.V1 / P2

V2 = 1 × 2.27 / 0.3

V2 = 7.567 L

Therefore, maximum limit to which the balloon can be inflated is 7.567 L.
