Thermos Index First Law of Thermodynamics
NonFlow Processes
Introduction The intrinsic internal energy U is the total internal energy minus the energies of motion, gravitational, magnetic and surface forces energies . The first law can be written using U as δQ = δU + δW This is termed the restricted energy conservation equation for a system The notes below relate to
various non flow processes using the restricted energy conservation equation when the
kinetic and potential and surface energies are assumed zero. Heating at constant volume
Adiabetic expansion in a cylinder
Free Expansion (Joules experiment)
Initially valve is closed and p_{A} > p_{B} > Heating at constant pressure
