10 Questions
Which law of thermodynamics sets no limit to the amount of total energy that can be caused to flow out as work?
First law
What does the first law of thermodynamics establish equivalence between?
Heat and work
What does the first law of thermodynamics not specify?
Conditions for heat transfer
Which law of thermodynamics states that heat will flow naturally from one energy reservoir to another at a lower temperature, but not in the opposite direction without assistance?
Second law
What is the purpose of a heat engine according to the second law of thermodynamics?
To convert heat into work
State the limitations of the first law of thermodynamics and the introduction to the second law.
The first law of thermodynamics does not specify the conditions for heat to be converted into work or the direction in which heat transfer can occur. The second law states that heat will naturally flow from a higher temperature energy reservoir to a lower temperature energy reservoir, but not in the opposite direction without assistance.
What is the second law of thermodynamics?
The second law of thermodynamics.
What does the first law of thermodynamics establish?
Equivalence between the quantity of heat used and the mechanical work.
What is the purpose of a heat engine according to the second law of thermodynamics?
A heat engine operates between two energy reservoirs at different temperatures.
What does the second law of thermodynamics state about the flow of heat?
Heat will flow naturally from one energy reservoir to another at a lower temperature, but not in the opposite direction without assistance.
