Question
A monatomic ideal gas initially has a temperature of 330k and preassure of 3x105 Pa. The gas expands from a volume of 500cm3 to a volume of 1500cm3.
l) Calculate the change in internal energy (in Joules), if the expansion is adiabatic.
answer => (150)ln(3)J
::::::DISCLAIMER:::::::
CALCULATE USING THIS EXACT FORMULA : Δu = g/2*pΔV
explain how to calculate 'p' in this case.
___________________________________________________________
Δu = g/2*n*r*ΔT
but, pΔV = n*r*ΔT
So, we could calculate the change in internal energy using Δu = g/2*pΔV
Again, use this formula to calculate Δu = g/2*pΔV
Don't calculate using Δu = g/2*n*r*ΔT
