pv graph of a carnot cycles is above..
My question is the C to D step it says that its a adiabatic compression.. so why there no significant change of the volume in the x axis in moving C to D?
and i know that step is reversible and the reversible processes take an infinite amount of time... But to make this happen adiabatically, dont we have to do that process very fast ? If not , how it is possible to stop the heat change ? I may have missed out something but Id be really grateful if someone could clear this out...
