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.

A system that does no work but which receives heat from the surroundings has?
A lower temperature.
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.
Is temperature a work done?
No, HEAT is work done!
It isn't possible to transfer heat from an object at a lower temperature to another object at a higher temperature unless?
It isn't possible to transfer heat from an object at a lower temperature to another object at higher temperature unless work is done to the system. An example of this is a refrigerator.
What is it called when a substance releases energy to its surroundings?
There are two ways that a substance ( called the System ) may release energy to the Surroundings :( 1 ) Heat may be released by heat transfer from the System to the Surroundings. Heat transfer from the System to the Surroundings requires the System temperature to exceed the temperature of the Surroundings and the presence of one or more heat transfer modes ( conduction, convection, and/or radiation.( 2 ) Work done by the System of on the Surroundings corresponding to a force moving through a distance, such as when the substance expands. Substance confined to a cylinder with a piston may expand, doing work on the Surroundings.

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 temperature a work done?
No, HEAT is work done!
Why entropy and temperature has inverse relation explain?
entropy is the measure of disorder in a system having direct relation with heat because it tells about the availability of heat more heat require to do useful work more is the entropy and having inverse relation with temperature because temperature tells the measure of agitation in an atoms of system that entropy is going to be measured.

It isn't possible to transfer heat from an object at a lower temperature to another object at higher temperature unless work is done to the system. An example of this is a refrigerator.
Is the heat supplied to a system always equal to the increase in its internal energywhat thermodynamic variable is defined by zeroth law and first law of thermodynamic?
The heat supplied to a system can increase its internal energy if no work is extracted from the system. If any work is done by the system, then the increase in internal energy will be less than the heat supplied to the system. The thermodynamic variable defined by the zeroeth law is Temperature.
What are the properties of heat and work?
Heat is a form of energy that results in a change in temperature or state of the system. Work refers to an activity that is being done on or by the system with the involvement of energy. Energy is the capacity to do work and is analogous to domestic currency. Both Work and heat (energy) are measured in Joules.
Define heat of work and how it is computed?
Define Heat of Work and Explain how it is computed.Heat of Work (HOW) is the the amount of heat added to refrigerant during the compression process. The heat content of the refrigerant at the outlet of the compressor (high-side) is subtracted from the heat content at the inlet of the compressor (low-side). The unit of measurement is in Btu/lbAnswerThere is no such thing as 'heat of work'. Heat and work are two different, but related, things. 'Heat' describes energy in transit from a higher temperature to a lower temperature, whereas 'work' describes energy in transit when one form of energy is converted into another form. The difference between work and heat is a measure of the rise in the internal energy of an object.
Is the work done in isothermal system is zero why?
If a reaction is carried out in constant temperature and constant volume no work is done and heat exchanged with surroundings is equal to the internal energy.
Is the work-done in isothermal system is zero why?
If a reaction is carried out in constant temperature and constant volume no work is done and heat exchanged with surroundings is equal to the internal energy.
