Question

adiabatic process?...........​

Answer 1

Answer:

It is the process in which no heat exchange takes place.

Explanation:

according to first law of thermodynamics, dQ=dU+dW

since in adiabatic process,no transfer of heat takes place. therefore, dQ=0.

therefore, dW= -- dU

in this process,work is done at the cost of internal energy of the system.

Answer 2

Answer:

An adiabatic process occurs without transfer of heat or mass of substances between a thermodynamic system and its surroundings. ... The adiabatic process provides a rigorous conceptual basis for the theory used to expound the first law of thermodynamics, and as such it is a key concept in thermodynamics.
