Determine the change in the internal energy of helium, in kJ/kg, as it undergoes a change of state from 100 kPa and 208C to 600 kPa and 3008C using the equation of state P(v 2 a) 5 RT where a 5 0.01 m3 /kg, and compare the result to the value obtained by using the ideal gas equation of state.
ANSWER:Step 1 of 4
The internal energy change of helium between two specified states is to be compared for two equations of states.
For helium, (Table A-2a)
