Heat, work, and internal energy are all forms of energy transfer. Heat is energy transfer due to a temperature difference, work is energy transfer due to a force acting through a distance, and internal energy is the total energy of a system. The change in internal energy of a system is the sum of the heat added to the system and the work done on the system.

What is the relationship between work, heat transfer, and change in internal energy in a thermodynamic system?

In a thermodynamic system, work, heat transfer, and change in internal energy are related through the first law of thermodynamics. This law 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. This relationship helps to understand how energy is transferred and transformed within 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 are the two ways in which internal energy can be transferred?

Internal energy can be transferred through heat and work.


What is the relationship between heat added to a system and the internal energy and external work done by the system-?

When heat is added to or is absorbed by a system, its internal energy increases. The amount of external work a system can do essentially refers to the amount of energy it can transfer to something else. So when internal energy increases, so does the external work done by the system.


What is the change in the internal energy of a system that does 100 joules?

The change in internal energy of a system that does 100 joules of work depends on the heat exchange as well. In general, the change in internal energy is equal to the amount of heat added to the system minus the work done by the system.

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.

What energy changes does a electrical heater have?

Electricity energy is converted into internal energy through work. As the internal energy of the heater increases so, too, does its temperature. Energy is then lost to the surroundings through heat transfer. The change in the heater's internal energy is the difference between the work done on the heater and the heat transfer away from it.


How are work and heat related?

because of the path functions ..Answer'Work' (symbol: W) describes the transfer of energy from one form into another. For example, an electric motor changes kinetic energy into electrical energy. 'Heat' (symbol: Q) describes the transfer of energy from a warmer body to a cooler body. For example, energy is lost from an electrical conductor if its temperature is higher than its surroundings. Scientists describe both work and heat as 'energy in transit'. Both share the same unit of measurement, the joule.In other words, work and heat are the only two methods of manipulating energy. And they are very much related to each other.For example, and electric kettle does work on the water by converting electrical energy into the internal energy (i.e. the energy associated with the vibration of atoms within any body) of the water (and of the kettle itself). This increase in internal energy results in the temperature of the water increasing above the ambient temperature and, so, energy is lost to the surroundings through heat transfer. So the amount by which the internal energy of the water has increased must be the difference between the work done on the water, and the heat transfer away from the water, that is:increase in internal energy = work - heatThis equation summarises the general relationship between work and heat.


When a system does work and no heat is added to the system its temperature?

remains constant From Rafaelrz. When a simple closed system does work and no heat is added, the temperature of the system will drop. This is because the work is done at the expense of his internal energy, which is thermal energy.


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 the internal energy of a system that does 5000 joules of work and absorbs 20000 joules of heat?

The internal energy change of the system would be the sum of the heat absorbed and the work done on the system. Therefore, the internal energy change would be 20000 J (heat absorbed) + 5000 J (work done) = 25000 J.


If work is don adiabatically on a system will the internal energy increase or decrease?

If work is done adiabatically on a system, the internal energy will increase. This is because adiabatic processes do not involve the exchange of heat with the surroundings, so any work done on the system will directly contribute to an increase in its internal energy.
