The first law of thermodynamics states that:
DU = DQ + DW
where DU is the increase in the internal energy of the gas
DQ is the heat supplied to the system
and DW is the work done ON the system
For an adiabatic process, DQ = 0
Therefore, DU = DW
It can be thus easily seen that for the internal to increase (DU +ve), DW must be positive, that is work has to be done on the system (in this case the ideal gas).
Hence, the gas should be compressed.

What is the relationship between the work done in an adiabatic process and the change in internal energy of a system?
In an adiabatic process, the work done is equal to the change in internal energy of a system.
Why does temperature of gas drops in an adiabatic process?
In an adiabatic process, no heat is exchanged between the system and its surroundings. When a gas expands without heat input, the gas does work on its surroundings and loses internal energy, leading to a decrease in temperature.
What is the work done in an adiabatic process?
In an adiabatic process, no heat is exchanged with the surroundings. The work done is the change in internal energy of the system, which is equal to the pressure times the change in volume.
Is in the adiabatic process change in internal energy is equal to change in work done?
In an adiabatic process, where there is no heat exchange with the surroundings, the change in internal energy is equal to the negative of the work done. This relationship is a result of the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.
What is an adiabatic process?
An adiabatic process is one in which there is no heat transfer into or out of the system. This means that any change in internal energy of the system is solely due to work done on or by the system. Adiabatic processes are often rapid and can lead to changes in temperature and pressure without heat exchange.
What is the relationship between the work done in an adiabatic process and the change in internal energy of a system?
In an adiabatic process, the work done is equal to the change in internal energy of a system.
How does the temperature of gas change when it is compressed if the process is adiabatic?
In an adiabatic process, the temperature is increased when it is compressed. There is an increase in internal kinetic energy, and because temperature is related to kinetic energy, it is also increased.
Why does temperature of gas drops in an adiabatic process?
In an adiabatic process, no heat is exchanged between the system and its surroundings. When a gas expands without heat input, the gas does work on its surroundings and loses internal energy, leading to a decrease in temperature.

Why do adiabatic temperature changes occur?
In adiabatic process heat is neither added nor removed from the system. So the work done by the system (expansion) in adiabatic process will result in decrease of internal energy of that system (From I st law). As internal energy is directly proportional to the change in temperature there will be temperature drop in an adiabatic process.
Is in the adiabatic process change in internal energy is equal to change in work done?
In an adiabatic process, where there is no heat exchange with the surroundings, the change in internal energy is equal to the negative of the work done. This relationship is a result of the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.

What is the relationship between the adiabatic process and the change in enthalpy (H) of a system?
In an adiabatic process, there is no heat exchange with the surroundings. This means that the change in enthalpy (H) of the system is equal to the change in internal energy (U).
What is the relationship between reversible adiabatic expansion work and the change in internal energy of a system?
During reversible adiabatic expansion, the work done by the system is equal to the change in internal energy.
What is adiabatic proccess?
An adiabatic process is one in which there is no transfer of heat between a system and its surroundings. This means that the change in internal energy of the system is solely due to work done on or by the system. Adiabatic processes are often characterized by a change in temperature without any heat exchange.
What happens to velocity in adiabatic expansion?
In adiabatic expansion, the velocity of a gas increases because the gas expands into a lower pressure environment, converting internal energy into kinetic energy. This increase in velocity is a result of the conservation of energy and the need to maintain equilibrium as the system adjusts to the changing conditions.
What is the work done by an adiabatic process?
The work done by an adiabatic process is the change in internal energy of a system without any heat transfer occurring. This means that the work done is solely due to changes in pressure and volume of the system.
