An isothermal process is the one in which temperature remains constant. The system is thermally conducting to the surroundings.
However, in an adiabatic process, the heat content remains constant and the system is thermally insulated from the surroundings.
Isothermal curve Adiabatic curve
change is PV = constant change is PVϒ = constant
2. Slope of isothermal change Slope of adiabatic change is
dP/dV = - (P/V) dP/dV = -ϒ (P/V)
3. The slope of isothermal curve The slope of adiabatic curve
is less compared to adiabatic curve is more compared to the other
4.The changes occurs slowly The changes occur suddenly
