Reversible means that in principle, the process is done infinitely slowly so that the microscopic reverse from the final state exactly regenerates the initial state. This requires an exact functional form of whatever term you are integrating. Isothermal just means constant temperature, i.e. ΔT=T2−T1=0 .

What is isothermal and adiabatic process?

The word 'isothermal' means constant temperature. An isothermal process is a process occurring at a constant temperature. ... Adiabatic process means a process that neither allows the heat to transfer inside nor let the heat out of the system.

What is the difference between isothermal and adiabatic process?

Ans: An isothermal process is a thermodynamic process in which there is no change in the temperature of the system. ... While an adiabatic process is the one in which there is no transfer of heat or mass in-between the system and the surrounding throughout the thermodynamic process. Hence, in an adiabatic system ΔQ = 0.

What does the term isothermal mean?

1 : of, relating to, or marked by equality of temperature. 2 : of, relating to, or marked by changes of volume or pressure under conditions of constant temperature.

What is isothermal process with example?

A refrigerator works isothermally. A set of changes take place in the mechanism of a refrigerator but the temperature inside remains constant. Here, the heat energy is removed and transmitted to the surrounding environment. Another example of an isothermal process is the heat pump.

What is called isothermal process?

An isothermal process is a change of a system, in which the temperature remains constant: ΔT = 0. ... In contrast, an adiabatic process is where a system exchanges no heat with its surroundings (Q = 0).

What is an isothermal process Class 11?

Isothermal Process: An isothermal process may be defined as a thermodynamic process in which the temperature remains constant. ... All the processes which are taking place inside a refrigerator are isothermal processes as there is no change in its internal temperature.

What is isothermal in science?

In thermodynamics, an isothermal process is a type of thermodynamic process in which the temperature of the system remains constant: ΔT = 0. ... In contrast, an adiabatic process is where a system exchanges no heat with its surroundings (Q = 0).

What is isothermal pressure?

An isothermal process is a change of a system in which the temperature remains constant: ΔT = 0. ... For an ideal gas, the product PV (P: pressure, V: volume) is a constant if the gas is kept at isothermal conditions (Boyle's law).

What is adiabatic process example?

The pendulum oscillating in a vertical plane is an example of it. A quantum harmonic oscillator is also an example of an adiabatic system. When we put the ice into the icebox, no heat goes out and no heat comes in.

What do you mean by adiabatic?

An adiabatic process is defined as a process in which no heat transfer takes place. This does not mean that the temperature is constant, but rather that no heat is transferred into or out from the system.

What is isothermal process Class 12?

Isothermal process: It is a process in which the temperature remains constant but the pressure and volume of a thermodynamic system will change. The ideal gas equation is. PV = µRT.

What does CP and CV mean?

CV and CP are two terms used in thermodynamics. CV is the specific heat at constant volume, and CP is the specific heat at constant pressure.

Why it is called isothermal expansion?

One condition, known as an isothermal expansion, involves keeping the gas at a constant temperature. As the gas does work against the restraining force of the piston, it must absorb heat in order to conserve energy. Otherwise, it would cool as it expands (or conversely heat as it is compressed).

What is isothermal and adiabatic process Class 11?

Hint: An isothermal process is a thermodynamic process that occurs under a constant temperature. Adiabatic process is a thermodynamic process that occurs without any heat transfer between a system and its surrounding.

What is meant by isothermal expansion?

The expansion of air under constant temperature. Since the air does work on expanding, it loses heat; consequently, heat must be added to the air to maintain it at constant temperature.

What are the benefits of compressing Isothermally?

Isothermal compression is significantly more energy efficient than adiabatic compression, but with the current standard compressor technologies isothermal compression is not possible as the compression process happens so fast. In most compressors, compression is almost 100% adiabatic.

When an ideal gas is isothermally compressed?

In the question it is said that when we compress an ideal gas isothermally, the pressure will increase. We are asked what causes the pressure to increase in such a situation. We know that when we compress a gas isothermally, its temperature is constant and volume of the gas decreases.

What is an isothermal compression?

Isothermal compression takes place when the heat of compression is removed during compression and when the temperature of the gas stays constant.

What is non isothermal?

By definition, isothermal means to have a constant temperature. Being nonisothermal flow refers to fluid flows with temperatures that are not constant. ... When a fluid is subjected to a temperature change, its material properties, such as density and viscosity, change accordingly.

What does Q stand for in thermodynamics?

Q represents the net heat transfer—it is the sum of all heat transfers into and out of the system. Q is positive for net heat transfer into the system. W is the total work done on and by the system. W is positive when more work is done by the system than on it.

What is a cyclic process in thermodynamics?

The process in which the initial and final state is the same is known as a cyclic process. It is a sequence of processes that leave the system in the same state in which it started. When a system undergoes a cyclic process, its initial and final internal energies are equal.

What is isothermal process Ncert?

Isothermal: - Iso means same and thermal related to temperature. In Isothermal process the temperature remains constant throughout while all other variables change. Temperature is constant throughout. For an ideal gas.

Does isothermal mean adiabatic?

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 .

What is irreversible and reversible process?

A reversible process is one in which both the system and its environment can return to exactly the states they were in by following the reverse path. An irreversible process is one in which the system and its environment cannot return together to exactly the states that they were in.
