    Can somebody take a stab at these 3 questions? I want to make sure I understand them correctly. Thank you in advance.

    Okay so I understand that an adiabatic process is a process in which the heat of the system stays constant. How does this happen?

    Also, how can a system do work and keep its temperature constant like in an isothermal process?

    What is the difference between heat and temperature?

    Summary:

    Adiabatic = no heat exchange, q = 0, deltaE = w. There is maximal change in temperature.

    Isothermal = fully conducting walls to the point where q = -w, deltaE = 0, since all work put in, simply escapes immediatly.

    Can anyone clarify what the difference between Adiabatic and isothermal is? I can't quite make it out using TPR or Chad's vids.

    Adiabatic is Δq=0, whereas isothermal is ΔT=0. Remember, heat is a measure of transfer of energy. It is a process. Temperature measures inherent, internal energy. It is not defined by an exchange of anything.

    Basically, adiabatic there is no change in heat (q); and isothermal, there is no change in temperature (T)
