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.
A system absorbs 640J heat and does work of 260J the change in internal energy of the system will be?
the system has been given internal energy of 640j and the work system does on surroundings is 260j. therefore by first law of thermodynamics the internal energy of system increases by (640-260=380)j.
When system does work what happens to it's internal energy?
When a system does work on its surroundings, its internal energy deceases. This is because some of the internal energy of the system is being used to perform the work.
What you conclude from adiabatic in joule experment?
In an adiabatic experiment, the system is isolated from its surroundings, so there is no heat exchange with the surroundings. The decrease in internal energy of the system is equal to the work done on the system. This relationship can be expressed by 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 a system which can exchange both matter and energy with its surroundings?
An open system is one that can exchange both matter and energy with its surroundings. This allows for a continuous flow of materials and energy in and out of the system, enabling it to maintain its internal balance despite changes in the surroundings.
What is the change in the internal energy of a system that absorbs 2.500J of heat and that does 7.655J of work on the surroundings is?
The change in internal energy is the sum of heat added to the system and work done by the system on the surroundings. So, the change in internal energy is 2.500J (heat absorbed) - 7.655J (work done), resulting in a change of -5.155J.
The system adsorbs energy from its surroundings?
The system absorbs energy from its surroundings, increasing its internal energy. This can lead to temperature increases or other forms of energy storage within the system. Adsorption is the process of collecting and retaining molecules on the surface of a material.
What is the change in internal energy if 20 joules of heat is released from a system and the system does 50 joules of work on the surroundings?
-70 Joules

A system gives off 196KJ of heat to the surroundings and the surroundings do 420 KJ of work on the system What is the change in internal energy of the system?
Δ E = -196 kj + 420 kJ = 224 kJ
When system does work what happens to it's internal energy?
When a system does work on its surroundings, its internal energy deceases. This is because some of the internal energy of the system is being used to perform the work.
A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10?
The surroundings do 4.20 x 10^3 J of work on the system, as work done by the surroundings is considered positive. The change in internal energy of the system is 196 kJ - 4.20 kJ = 191.8 kJ. This change includes the energy flow as heat and work.

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).
When reactants change to products do the chemicals lose or gain energy?
The formation of bonds causes an energy release, while the breaking of bonds causes an absorption of energy. In a combustion reaction c+o2 --> co2, the reactants have a higher internal energy than the products resulting in a negative internal energy because energy is flowing out of the system to the surroundings. However in co2 ---> c+o2, the reactants have a lower internal energy than the products, so the internal energy of the system is positive as energy is flowing into the system from the surroundings.
