Question
One kg of a diatomic gas is at a pressure of 8 × 104 N/m2. The density of the gas is 4 kg/m-3. What is the energy of the gas due to its thermal motion?
Options
A.3 × 104J
B.5 × 104J
C.6 × 104J
D.7 × 104J
Solution
Thermal energy corresponds to internal energy
Mass = 1 kg
density = 8 kg/m3
⇒ Volume =
Pressure = 8 × 104 N/m2
∴ Internal Energy
P × v = 5 × 104 J
Mass = 1 kg
density = 8 kg/m3
⇒ Volume =
Pressure = 8 × 104 N/m2
∴ Internal Energy
P × v = 5 × 104 JCreate a free account to view solution
