First law of thermodynamics
work done on the gas
when a gas is compressed
Pressure volume diagram
describing the changes of volume and pressure
isobar
pressure remains constant
isovolumetric
volume remains constant
isothermal
heat remains constant regardless of its exposure
adiabatic
heat remains constant within the system
its a cycle, therefore no net change
dQ=dU+dW
W = energy by the gas (expansion)
U = Energy on the gas (compression)
Q = Heat transfer
work done by the gas
p21(v2-v1)
When a gas expands
