Chestermiller replied to the thread High School Internal energy and gravitation.The more general form of the 1st law of thermodynamics is $$\Delta U+\Delta (PE)+\Delta (KE)=Q-W$$where PE is the gravitational... -
Chestermiller replied to the thread Pressure-Volume Work.At any point during the process, the pressure P is related to the mass m by $$PA=mg$$or $$m=\frac{PA}{g}$$Therefore, mass can be used as...

Chestermiller replied to the thread Pressure-Volume Work.The total work is path independent, but the path for adiabatic reversible is different from the path for isothermal reversible, and the...

Chestermiller replied to the thread Pressure-Volume Work.Initial pressure = ##P_0A=m_0g##, where ##m_0## is the finite amount of mass that must be added to the piston to hold it in equilibrium...
