Explain the Difference between adiabatic and isothermal compression?

Answer 1

"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).

Answer 2

In adiabatic compression, there is no heat exchange with the surroundings, so the temperature of the gas increases as it is compressed. In isothermal compression, the temperature of the gas remains constant during compression because any heat generated is dissipated to keep the temperature constant.

Answer 3

An adiabatic compressor does not exchange heat with its surroundings so the temperature of the compressed material will increase, in an isothermal compressor the material's temperature is kept constant by expelling heat to it's surroundings.

Answer 4

Adiabatic expansion is an increase in volume while pressure is maintained constant. When this occurs, temperature also increases.

Isothermal expansion is an increase in volume while temperature is maintained constant. When this occurs, pressure decreases.

Answer 5

Isothermal process is going on under constant temperature, adiabatic is a process where no heat is exchanged (this does not imply that temperature is constant).

Answer 6

Adiabatic means without any transfer of heat, and isothermal means having only one constant temperature.
