What scientific principle says that natural processes tend to go toward less usable energy and greater disorder?
The Second Law of Thermodynamics is about the quality of energy. It states that as energy is transferred or transformed, more and more of it is wasted. The Second Law also states that there is a natural tendency of any isolated system to degenerate into a more disordered state.
Which branch of physics deal with heat and thermal energy?
Thermodynamics
Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.
What is the idea that the universe is lawful orderly and operates according to physical laws?
Ch. 1-5
| Term or Question | Answer or Definition |
|---|---|
| states that the universe is lawful, orderly, and operates according to physical laws | principle of causality |
| energy of motion | kinetic energy |
| device used to measure the change in heat | calorimeter |
| transfer of thermal energy without matter | radiation |
What device uses a double walled container and an insulating stopper to keep liquefied gases cold?
A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask’s surroundings.
Who proposed 2nd law of thermodynamics?
Rudolf Clausius
Rudolf Clausius developed the second law of thermodynamics without appealing to the caloric theory of heat. He defined an important property called entropy that emerges directly from the basic postulates of Sadi Carnot.
What does the 2nd law of thermodynamics state?
For… In philosophy of physics: Thermodynamics. The second law of thermodynamics states that the total entropy of an isolated system (the thermal energy per unit temperature that is unavailable for doing useful work) can never decrease.
What is the law of conservation of energy also known as the first law of thermodynamics?
The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. “So, it’s a restatement of conservation of energy.”
What law of thermodynamics states that heat of itself never flows from cold object to a hot object?
The Second Law of Thermodynamics(first expression): Heat transfer occurs spontaneously from higher- to lower-temperature bodies but never spontaneously in the reverse direction. The law states that it is impossible for any process to have as its sole result heat transfer from a cooler to a hotter object.
What is defined as the portion of the universe being studied?
A system is the specific portion of the universe that is being studied. Everything outside the system is considered the surroundings or environment.
What is the study of interactions between matter and energy?
Physics is the science of matter and energy and their interactions and motion through space and time.
What idea explains that molecules of an object move faster as the object is heated?
Heat, once absorbed as energy, contributes to the overall internal energy of the object. One form of this internal energy is kinetic energy; the particles begin to move faster, resulting in a greater kinetic energy. This more vigorous motion of particles is reflected by a temperature increase.
