Question

please solve this problem ​

Answer 1

Given :

• Volume of hydrogen in cylinder = 9L
• pressure at which hydrogen is kept = 10 atm
• Pressure of balloon = 2 atm
• Volume of one balloon = 1 L
• Temperature is constant

To find :

Number of balloon (n) that can be filled from cylinder.

Solution :

At constant temperature, we will use

• Pressure × Volume = Constant

$\sf \implies \: P_1 \times V_1 \: = \: n \: \times \: P_2 \times V_2$

$\sf \implies \: 10 \: atm \times 9 \: L\: = \: n \: \times \: 2 \: atm \times 1 \: L$

$\sf \implies \:90 \: = \: n \: \times \: 2$

$\sf \implies \: \: n = \: \dfrac{90}{2}$

$\sf \implies \: \: n = \bold{45}$

ANSWER :

Number of balloon (n) filled = 45
