What is steam temperature after adiabatic expansion?
lower
Which thermodynamic process gives maximum work?
Reversible adiabatic expansion/compression
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.
Adiabatic processes cause cooling by?
Adiabatic cools by decompression.
Is melting process is adiabatic process?
An adiabatic process in the opposite of a diabatic process. The adiabatic process occurs without the exchange of heat with its environment. A diabatic process exchanges heat with the environment.
What is steam temperature after adiabatic expansion?
lower
What is cooling of air expansion caused by?
adiabatic cooling
Why does gas inside a cylinder cool when subjected to adiabatic expansion?
because while cooling of gas in adiabatic expansion process , as it is a reversible procces the heat is lost while reversible work
Which thermodynamic process gives maximum work?
Reversible adiabatic expansion/compression
What happens when adiabatic expansion of gas molecules occurs?
The temperature of the gas decrease.
Changes in temperature that result solely from the expansion or compression of air are called?
adiabatic
What is free expansion in thermodynamics?
In free expansion, the external pressure is zero, i.e. work done is zero. Accordingly, free expansion is also called irreversible adiabatic expansion.
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.
What are the condition for ideal fluid?
1.Isothermal expansion at a high temperature AB 2.Adiabatic expansion as the temperature falls to a lower rule BC 3.Isothermal compression at lower temperature CD 4.Adiabatic compression as temperature increase to initial high volume DA
When a gas undergoes adiabatic expansion it gets cooled due to?
It gets cooled because the internal energy of the system decreases.
Is entropy of adiabatic compression increase or decrese?
entropy of system for a reversible adiabatic process is equal to zero. entropy of system for a irreversible adiabatic process (like free expansion) can be achieved by the following formula: Delta S= n Cp ln(V2/V1) + n Cv ln (P2/P1)
