A balloon having weight 50 kg is filled with 685.2 kg of helium gas at 760 mm pressure and 25° C. What will be its pay load if it displaces 5108 kg of air?

Question

A balloon having weight 50 kg is filled with 685.2 kg of helium gas at 760 mm pressure and 25° C. What will be its pay load if it displaces 5108 kg of air? (A) 4372.8 kg (B) 4392.6 kg (C) 4444.4 kg (D) 3482.9 kg

Tardigrade Admin · Accepted Answer

Mass of the filled balloon =50+685.2=735.2 kg Pay load = Mass of displaced air - Mass of balloon =5108- 735.2=4372.8 kg

Q. A balloon having weight $50 k g$ is filled with $685.2 k g$ of helium gas at $760 mm$ pressure and $2 5^{\circ} C$ . What will be its pay load if it displaces $5108 k g$ of air?

4372.8 kg

4392.6 kg

4444.4 kg

3482.9 kg

Mass of the filled balloon
$= 50 + 685.2 = 735.2 k g$
Pay load $=$ Mass of displaced air $-$ Mass of balloon
$= 5108 - 735.2 = 4372.8 k g$
