How can you differentiate between adiabatic and isothermal process in PV graphs?
How can you differentiate between adiabatic and isothermal process in PV graphs?
The paths look somewhat similar on the P-V diagram, but you should notice clear differences. Note that an isothermal process has no change in temperature, so the change in internal energy is zero, but in an adiabatic process the heat transferred is zero.
What is the slope of an adiabatic line and isothermal line on PV diagram?
Isothermal curve slope = γ×adiabatic slope.
What is the relation between slope of isothermal and adiabatic curves?
(b) Isothermal curve slope = γX adiabatic curve slope.
What do you mean by isothermal and adiabatic curve?
The curve showing the relation between pressure and volume of a given mass of gas when the flow of heat into or out of the gas is stopped is called its adiabatic curve. It is represented by the equation. pv γ = constant. where. If isothermal and adiabatic curves be plotted on the same p–v diagram (Fig.
Why are adiabatic curves steeper than isothermal curves?
Adiabatic process is a rapid process. The pressure and temperature changes occur at faster rate so its curve is steeper than isothermal curve.
Which curve is steeper adiabatic or isothermal?
adiabatic curve
Hence the adiabatic curve is steeper than the isothermal curve, in both the processes of expansion and compression.
Why is PV curve for adiabatic process steeper than that for isothermal process?
Answer. As γ is always greater than 1, the slope of an adiabatic curve is greater than that of an isothermal curve by a factor of γ. Hence the adiabatic curve is steeper than the isothermal curve, in both the processes of expansion and compression.
How do you tell if a process is adiabatic or isothermal?
isothermal is the process where WORK is done between the same temperature difference,whereas in adiabatic the work is done where there is NO heat or temperature difference is there .
Why is the PV curve for an adiabatic?
Expert-verified answer As γ is always greater than 1, the slope of an adiabatic curve is greater than that of an isothermal curve by a factor of γ. Hence the adiabatic curve is steeper than the isothermal curve, in both the processes of expansion and compression.
Why is the PV curve for adiabatic process steeper than that of isothermal process?
