Second Law of Thermodynamics
... In the p-V diagram below , isotherms are distinguished by differences in temperature and the adiabats by differences in potential temperature θ. There is another way of distinguishing differences between adiabats. In passing from one of the adiabats (θ1 or θ2) to another along an isotherm (this is a ...

... The change in energy ∆U or ∆E is independent of the path by which the transformations are carried out. It depends only on the initial and final states of the system. Hence energy is a state function. The actual value of internal energy cannot be determined. In thermodynamics, the absolute value of i ...

The cross-sectional area of the launch tube is 1.0 cm2, and the length that the projectile travels down the tube after starting from rest is 32 cm. As the gas expands, the pressure varies as shown in Figure P12.4b. The values for the ini ...

... (16 pts) Problem 6. An engine using 0.12 moles of a diatomic ideal gas is driven by this cycle: starting from state A, the gas is compressed isothermally until it reaches state B. Then, the gas is heated at constant pressure until it reaches state C. Finally, the gas is cooled at constant volume ba ...
