Question
The decrease in internal energy of a 125-kg ideal
gos is 345 kJ when the pressure decreases from 690
The decrease in internal energy of a 1.25-kg ideal
gas is 345 kJ when the pressure decreases from 690
kPaa to 138 kPaa and the volume decreases from
0.05 m to 0.14 m2. if c, 0.6188 kJ/kgK, what is the
Initial temperature in K?
Expert Answer
Step 1
Process can be determined as
PV" = PV"
