Explain the Difference between adiabatic and isothermal compression?
"Adiabatic process" refers to processes that take place in a closed system with no heat interaction with it's surroundings. "Isentropic process" refers to processes that take place in a closed system with no heat interaction with the surroundings (adiabatic process) and internally reversible. This is, no internal generation of entropy, entropy stays constant, which is what is meant by "isentropic". We can also say, an isentropic process is one where entropy stays constant, and no heat interaction of the system with the surroundings takes place (adiabatic process). Or, an adiabatic process can be irreversible, or reversible (isentropic).
Why carnot cycle is called a two adiabatic and two isothermal process?
Adiabatic means there's no heat transference during the process; Isothermal means the process occurs at constant temperature. The compression and expansion processes are adiabatic, whereas the heat transfer from the hot reservoir and to the cold reservoir are isothermal. Those are the two adiabatic and isothermal processes.
Why does the temperature remains constant during the change of state?
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
Which property remains unchanged during an adiabatic saturation moist air?
Wet bulb temperature
Why does adiabatic expansion of a gas always produce cooling?
During adiabatic expansion, a gas expands without gaining or losing heat to its surroundings. This causes the gas to do work on its surroundings, which in turn lowers the internal energy of the gas. Since temperature is directly related to the internal energy of a gas, the temperature of the gas decreases during adiabatic expansion, resulting in cooling.
How does enthalpy change during adiabatic expansion?
During adiabatic expansion, enthalpy remains constant.
What is different between adiabatic system and isothermal system?
An isothremal process is one in which the temperature is constant. heat can be gained or lost in order to maintain a constant tempereature. An adiabatic process is one in which there is no heat exchange between a system and its surroundings. It does not matter whether the temperature of the system is constant or not.

Why an adiabatic curve steeper than an iosthermal?
In isothermal the temperature is constant whereas in adiabatic the temperature falls or rises rapidly.Consider the case for expansion where in adiabatic the temperature drops. If you consider PV/T=constant then for same pressure we can show that as temp decreases the volume also decreases. During expansion for isothermal the temp does not change so volume is higher than adiabatic. Example: Isothermal P=8 Pa, V=x , T=2K Adiabatic P=8 Pa, V=y, T=1K (as it drops) Using PV/T=constant we can find that y is less than x.

What is steam temperature after adiabatic expansion?
The steam temperature after adiabatic expansion depends on the specific conditions of the expansion process, such as initial temperature, pressure, and volume. During adiabatic expansion, the internal energy of the steam decreases, causing its temperature to drop. The final temperature can be determined using the appropriate thermodynamic equations.

During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
What is the relationship between entropy and adiabatic expansion?
During adiabatic expansion, entropy remains constant. This means that as a gas expands without gaining or losing heat, its entropy does not change.
What is the relationship between enthalpy and temperature change during an adiabatic expansion process?
During an adiabatic expansion process, there is no heat exchange with the surroundings. As a result, the change in enthalpy is directly related to the change in temperature. When a gas expands adiabatically, its temperature decreases, leading to a decrease in enthalpy.
Which property remains unchanged during an adiabatic saturation moist air?
Wet bulb temperature
How can one calculate the work done during an adiabatic reversible expansion process?
To calculate the work done during an adiabatic reversible expansion process, you can use the formula: work -nRT ln(V2/V1), where n is the number of moles of gas, R is the gas constant, T is the temperature, and V1 and V2 are the initial and final volumes of the gas.
Is it possible to compress an ideal gas isothermally in an adiabatic piston cylinder device?
No, it isn't. This is because the first law relation Q - W = ΔU reduces to W = 0 in this case since the system is adiabatic (Q = 0) and ΔU = 0 for the isothermal processes of ideal gases. Therefore, this adiabatic system cannot receive any net work at constant temperature.
