The law governing changes in energy is primarily encapsulated in the first law of thermodynamics, which states that energy cannot be created or destroyed, only transformed from one form to another. This means that when energy changes from, for example, kinetic to potential energy, the total energy in a closed system remains constant. Additionally, the second law of thermodynamics addresses the direction of these energy transformations, indicating that energy tends to disperse or spread out, leading to increased entropy in isolated systems.
What else can I help you with?
To say that energy levels in an atom are discrete is to say the energy levels are well defined and?
quantized, meaning they can only have certain specific values. This quantization results in distinct energy levels for electrons in an atom, leading to the emission or absorption of photons when electrons transition between these levels.
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!
What are the changes an organism goes through during its lifetime?
Organisms typically go through growth and development, including changes in size, structure, and function. They may also undergo changes related to reproduction, such as maturation and aging. Environmental factors can also influence an organism's development and behavior throughout its lifetime.
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 phase changes involve the release of heat?
The phase changes that involve a release of heat are those in which the particles move closer together. Thus, freezing is one phase change that involves a release of heat. The other such change is condensation.
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 is the process when a solid turns to gas?
it is called deposition
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.
Law that states that energy cannot be created or destroyed?
The law that states energy cannot be created or destroyed is the First Law of Thermodynamics. It is also known as the Law of Conservation of Energy, which states that energy can only change forms or be transferred from one system to another.
What does the first law of thermodynastics say?
The first law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another. It is also known as the law of conservation of energy.
The Two branches of physical science are?
The two branches of physical science are physics and chemistry. Physics explores the fundamental principles governing matter, energy, and motion, while chemistry focuses on the composition, structure, and properties of substances and the changes they undergo.
What does the law of conservation of energy say about energy?
The law of conservation of energy states that energy cannot be created or destroyed, but can only be converted from one form to another. This means that the total amount of energy in a closed system remains constant over time.
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 .
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.
Why do we say that chemical reactions always involve changes in energy?
Chemical reactions involve the breaking and forming of chemical bonds, which requires energy to overcome or release. This results in changes in the potential energy of the system. Additionally, the activation energy required to start a chemical reaction is a clear demonstration of energy change.
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)
