<h3>
Answer:</h3>
24.94 L
<h3>
Explanation:</h3>
<u>We are given;</u>
- Moles of Helium, n= 1 mole
- Pressure of the gas, P = 100 kPa
- Temperature of the gas, T = 300 K
We are required to calculate the volume of the balloon
- We are going to use the ideal gas equation;
- According to the ideal gas equation;
PV = nRT , where R is the ideal gas constant, 8.314 L.kPa/mol.K
V = nRT ÷ P
= ( 1 × 8.314 × 300 K) ÷ 100 kPa
= 24.94 L
Therefore, the volume of the balloon is 24.94 L
Answer:
2nd option
Explanation:
total energy = kinetic energy + potential energy
and since
kinetic energy = 456J
total energy = 8768 J
substitute these values into the equation
8768 = 456 + potential energy
potential energy = 8312 J
