What is the relationship between the work done by an expanding gas and the change in its internal energy?
The work done by an expanding gas is directly related to the change in its internal energy. When a gas expands, it does work on its surroundings, which can lead to a change in its internal energy. This change in internal energy is a result of the work done by the gas during the expansion process.
What type of work is performed during the expansion of the gas?
During the expansion of gas, work is performed as the gas pushes against a piston or moves a turbine, resulting in the transfer of energy.
How is energy different from work?
They have the same units- Joules - so can be equated. Work is something actually done, and in doing work energy is expended, but you can also talk of doing work to store energy. For example in running a compressor to fill a cylinder with compressed gas, energy is supplied to the compressor motor, work is done by the compressor, and the result is stored energy in the gas. Fuels such as coal have potential or stored energy, which can be released to do work. So I think the fundamental is energy, but when energy is used, work results. Hope that makes sense!
In Adiabatic process how the ideal gases increases it's internal energy?
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.
1. 10 J of heat are removed from a gas sample while it is being compressed by a piston that does 20 J of work. What is the change in thermal energy of the gas Does the temperature of the gas increase?
10 JoulesConservation of energy, assuming there are no other losses in the system, and 20 Joules are introduced by compression, and 10 Joules are removed by heat transfer, the remaining 10 Joules must be absorbed as increased thermal energy of the gas.
What is the relationship between the work done by an expanding gas and the change in its internal energy?
The work done by an expanding gas is directly related to the change in its internal energy. When a gas expands, it does work on its surroundings, which can lead to a change in its internal energy. This change in internal energy is a result of the work done by the gas during the expansion process.
What happens to the internal energy of a gas when it expands?
When a gas expands, its internal energy typically increases. This is because the gas is doing work on its surroundings as it expands, which results in an increase in its internal energy.
What is energy is transferred to a gas as heat and work If there is no change in its internal energy the process is known as?
The process is known as an isothermal process. In an isothermal process, the energy transferred to the gas as heat and work results in no change in the gas's internal energy because the temperature remains constant throughout the process.
What type of work is performed during the expansion of the gas?
During the expansion of gas, work is performed as the gas pushes against a piston or moves a turbine, resulting in the transfer of energy.
When a gas undergoes adiabatic expansion it gets cooled due to?
the decrease in pressure causing the gas to expand and do work on its surroundings. This work requires energy, which is taken from the internal energy of the gas, leading to a decrease in temperature. This cooling effect is a result of the conservation of energy in an adiabatic process.

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 spiral pipe is used in linds method for liquificattion?
when highly compressed gas pass from spiral pipe (at decrease heat of intecompression,by using refrigerating liquid) in zig zag pipe a gas have already decreased energy and doing work for movement to goahead for doing work gas molecules lose energy for doing such work.and when gas pass through nozzal then gas molecules move apart,using energy from itself and then gas molecules energy decreased and become cool means enter in a high pressure region to low pressure region.
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.
