To say that energy levels in an atom are discrete is to say the energy levels are well defined and?
That because only certain photons are emitted, we know that only certain energy changes are occurring.
Why do changes in temperature often happen during chemical change?
This is due to changes in energy. Look at the chemical reaction A + B --> C . Say it requires a lot of energy for A and B to react together, but very little energy to keep C as C. All the energy you put into the reaction to make A and B turn into C will be released as heat once C is formed. However if it requires a lot of energy to keep C as C after the reaction happens, then the reaction will seem cold because it is taking energy in the form of heat out of its surroundings!
How is energy converted from potential energy to kinetic?
The conversion of potential energy to kinetic energy follows "The Law of Conservation of Energy."Energy cannot be created or destroyed. In a closed system it just changes form.The total amount of energy in the universe does not increase nor decrease. It only changes forms.So, if before big bang the universe was pure kinetic, it is now mostly potential. How much further can the energy disperse before gravity pulls it all back together into another big bang? just kidding...
What was Sir Isaac Newton's theory on thermal dynamic energy?
Sir Isaac Newton did not speak directly to the laws of thermal dynamics but he did say "Energy is not lost or destroyed, it is merely transferred from on party to the next.''Which is similar to, the first law of thermodynamics. "The total energy of an isolated system is constant; energy can be transformed from one form to another, but cannot be created or destroyed. "
What name is given to the property by which objects resist changes in motion?
Inertia is the tendency of an object to resist changes in its motion. This is, in essence, the statement of Newton's first law. The concept of inertial is quantified by mass. We say an object with twice the mass has twice the inertia. See also the related question link.
What branch changes a unconstitutional law?
The judicial branch can say if a law is unconstitutional.
What is the process of a solid turning into a gas is called?
When a solid changes state directly into a gas, we say it will sublime, or undergo sublimation.
What does law of conversion of energy say?
The law of conservation of energy states that "energy can not be created (made) or destroyed (made gone)"
What is the process when a solid turns to gas?
it is called deposition
Why do we say that chemical reactions always involve changes in energy?
Because they do. In fact, you can't get ANYTHING done without some energy changes involved.
Law that states that energy cannot be created or destroyed?
The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.
To say that energy levels in an atom are discrete is to say the energy levels are well defined and?
That because only certain photons are emitted, we know that only certain energy changes are occurring.
What is the law of conservation in your own words?
There are many different laws of conservation, but they are essentially the same. For this example I will use energy. The laws of conservation of energy say that energy in = energy out. This is to say that energy cannot be destroyed or created.
Example of law conservation of energy?
Let's say that everything is an example of the Law of Conservation of Energy - because this is a law that has never been seen to fail. More specifically, in any energy conversion, one type of energy gets reduced; another type of energy inreases in the same amount.
What is the first law of thermodynamics known as?
The first law is also known as law of conservation of energy. It say that the energy can neither be created nor be destroyed but can only be transferred. Its is given by this equation dQ = dU + dW .
Can you use friction and the law of conservation of energy in the same sentence?
Say this "even when friction occurs and physical changes take place, the law of conservation of mass states that no matter is lost in the process". (though it may seem like matter has been lost, some of the matter goes in the atmosphere or onto the ground depending on what you are applying friction too)
What is the first law of thermodynamics also known as?
