Answer:
200 Joules is the explosive energy in the inside the balloon. And that is [tex]9.523\times 10^{-5} [/tex]1 lb of TNT.
Explanation:
[tex]Pressure=\frac{force}{Area}=\frac{Force\times distance}{Area \times distance}=\frac{Energy}{Volume}[/tex]
Volume of the balloon = V = 1 L = [tex]0.001 m^3[/tex]
Pressure inside the balloon ,P= 200,000 Pa =[tex]200,000 N/m^2[/tex]
Explosive energy in the inside the balloon be E.
E = Pressure × Volume
[tex]E=200,000 N/m^2\times 0.001 m^3=200 Joules[/tex]
1 lb of TNT = [tex]2.1\times 10^6 J[/tex]
200 Joules = [tex]200\times \frac{1}{2.1\times 10^6 }[/tex]1 lb of TNT
= [tex]9.523\times 10^{-5} [/tex]1 lb of TNT
