What is isothermal expansion and compression?

What is isothermal expansion and compression?

In the isothermal compression of a gas there is work done on the system to decrease the volume and increase the pressure. Doing work on the gas increases the internal energy and will tend to increase the temperature. For isothermal expansion, the energy supplied to the system does work on the surroundings.

What is the definition of isothermal compression?

i. Reduction in the volume of a fluid without any change in its temperature.

What is adiabatic expansion and compression?

The adiabatic compression of a gas causes a rise in temperature of the gas. Adiabatic expansion against pressure, or a spring, causes a drop in temperature. In contrast, free expansion is an isothermal process for an ideal gas.

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 is meant by adiabatic expansion?

Expansion in which no heat is added to or subtracted from the air, which cools during the expansion because of the work done by the air.

What is the difference between isothermal expansion and adiabatic expansion?

ISOTHERMAL — No change in temperature occurs during a thermodynamic exchange and therefore U = 0. The expansion is SO SLOW that no change in temperature occurs and the internal energy is static. Almost like watching paint dry. ADIABATIC — No change in heat occurs during a thermodynamic exchange and therefore Q = 0.

What is adiabatic expansion in physics?

What is Adiabatic Expansion? Adiabatic expansion is defined as an ideal behaviour for a closed system, in which the pressure is constant and the temperature is decreasing.

What is isothermal process class11?

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 happens isothermal expansion?

Hint: The isothermal expansion means a gas is expanding from initial volume to final volume at constant temperature. The internal energy and enthalpy depend upon the temperature only in case of ideal gas. So, during the isothermal expansion of an ideal gas, the temperature remains constant and volume increases.

What is isothermal and adiabatic expansion?

What is meant by an isothermal compression and adiabatic compression?

Isothermal compression requires heat transfer to the surroundings to maintain constant temperature, lowering the pressure of the system and thus lowering the resistance to compression compared to the adiabatic compression (where heat exchange is not allowed).

What is the difference between adiabatic compression and isothermal compression?

As per the thermodynamic terminology, in the adiabatic process, there is no exchange of heat from the system to its surroundings neither during expansion nor during compression. Whereas in the isothermal process, the temperature remains constant throughout the work.
