When is a thermodynamic work said to be positive?
In thermodynamics, work done by a system on its surroundings or another system is said to be positive.
What is the study of relationships between heat work and thermal energy?
Thermodynamics is the study of the relationship between thermal energy and heat and work.
Is Thermodynamics the study of the relationships among heat work and other forms of energy?
Yes this is correct."Thermodynamics is the study of the relationships among heat, work and other forms of energy."
How does the thermal energy of a system change when work is done on The system?
Usually the "thermal energy" will increase since work ON the system adds energy. Thermal energy is really not the best term though. A much better term in thermodynamics would be ENTHALPY.
What is The first law of Themodynamics?
* First law of thermodynamics, about the conservation of energy: : :: The change in the internal energy of a closed thermodynamic system is equal to the sum of the amount of heat energy supplied to the system and the work done on the system. --from Wikipedia
When is a thermodynamic work said to be positive?
In thermodynamics, work done by a system on its surroundings or another system is said to be positive.
What is the study of the flow of energyheat and work?
The answer is "Thermodynamics"
What law of thermodynamics is unavailable for doing work?
"Unavailable for doing work" is related to the Second Law of Thermodynamics.
How does Thermodynamics affect the work of mechanical engineers?
thermodynamics, is essential for mechanical engineers, because the subject is mainly about heat and work in system, and as an engineer that is important, especially when you have to design engines, because that is when you have to determine important factors such as the amount of work that can be done by that engine internally, and the heat it transefered and obtained.
What is squaw work and men work mean?
Squaw is a vulgar reference to a Native American woman. This idiom means work that is typically done by woman and work that is typically done by men.
Work done is not a state function?
In mechanics,work done(work=force.displacement of body) by a body is independent of path.It only depends on the initial and final state of the body.However in thermodynamics,the work done by an ideal gas(work=pressure.change in volume of gas) depends on the path taken(isochoric,isothermal,isobaric,adiabatic)
When facing a new project you have never experienced at work how do you typically get the work done?
no
What are the consequances of first law of thermodynamics?
According to the first law of thermodynamics energy can neither be created nor be destroyed and any change in energy of a system is accounted for by work done. The work-energy relationship is the foundation on which all engines and motors operate, including the human engine. Energy gets converted into other forms of energy or it gets used to do work.
What is the study of relationships between heat work and thermal energy?
Thermodynamics is the study of the relationship between thermal energy and heat and work.
What is free expansion in thermodynamics?
In free expansion, the external pressure is zero, i.e. work done is zero. Accordingly, free expansion is also called irreversible adiabatic expansion.
Is in adiabatic process the work done is independent of path?
YES.. By first law of thermodynamics, dQ=dW+dU For adiabatic process dQ=0 dW=-dU Above relation shows that the work done is equal to change in internal energy in magnitude which is the property of the system or point function. Thus work done in adiabatic process is a point function.
Is Thermodynamics the study of the relationships among heat work and other forms of energy?
Yes this is correct."Thermodynamics is the study of the relationships among heat, work and other forms of energy."
