The amount of energy available to do work after a chemical reaction has occurred is called?
The amount of energy available to do work after a chemical reaction has occurred is called free energy or Gibbs free energy. It represents the maximum amount of useful work that can be obtained from a system at constant temperature and pressure.
Is the total energy of the universe becoming more unavailable with time?
Yes, according to the Second Law of Thermodynamics, the total energy in the universe is becoming increasingly unavailable for doing work. This is because energy tends to disperse and become more evenly distributed over time, leading to a decrease in the amount of energy available to do useful work.
The amount of energy in a chemical that can do useful work is called?
This would be its chemical potential energy, of course it depends on what other chemical(s) it is reacting with, such as oxygen.
What is a 2nd law of energy?
You must be referring to the two Laws of Thermodynamics. Stated in terms of energy: 1. The First Law of Thermodynamics is the Law of Conservation of Energy, meaning that energy can not be created or destroyed. 2. However, useful energy is continuously being converted into unusable energy. This is irreversible. This is the Second Law of Thermodynamics.
If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out of a light bulb is primarily in the form of light and heat. The electrical energy is converted into light energy that illuminates the surroundings and heat energy that warms up the light bulb and its surroundings.
An airplane changes energy into different forms The total amount of energy does not?

Why does the amount of useful energy decrease when energy changes from one form to another?
Conversions of energy forms are lossy. For example, when mechanical energy is converted to electrical energy (such as happens in an electric generator), there is friction which leads to the escape of heat and sound energy. While the total amount of energy in all forms remains constant, the heat and sound energy are next to impossible to recapture, so this is considered a loss of useful energy.
If energy cannot be created nor destroyed why does its value sometimes decrease or increase?
The conservation of energy principle states that the total amount of energy in a closed system remains constant. However, energy within the system can change forms or transfer between objects, resulting in changes in its value. This can manifest as an increase or decrease in the amount of useful or available energy for performing work.
Why is the amount of useful output energy always less than the input energy?
The reason the useful output energy is always less than the input energy is due to inefficiencies in the energy conversion process. Some energy is always lost as heat, sound, or other forms of energy during conversion, reducing the amount of energy available for useful work. This decrease in useful output energy is described by the concept of energy conservation and the second law of thermodynamics.
A comparison of amount of energy before a conversion with the amount of useful energy after a conversion?
Usually, the amount of useful energy after a conversion will be less than the original energy. In no case can it be more.Usually, the amount of useful energy after a conversion will be less than the original energy.

What is the name of the amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
During an energy transfer what happens to the total amount of energy?
Energy can not be destroyed, so the total amount of energy before a change is equal to the amount of energy after the change. However, some energy is changed into a useful form, but some may be wasted and not used. For example, a light bulb, changes electrical energy into light energy, but some of the energy is changed to heat and some to sound, these are not useful and are wasted, but are changed nonetheless. So a transformation from mechanical energy to heat will have the same total energy at the start as at the finish, but unless it is 100% efficient some of the original energy will be 'lost'
What is a useful amount of energy you get from a system?
It is energy officenty
What is the name of energy amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
What is the amount of useful energy you get from an energy conversion called?
The amount of useful energy obtained from an energy conversion process is referred to as energy efficiency. It is calculated by dividing the useful output energy by the total input energy and expressing it as a percentage. Energy efficiency is an important factor in determining the overall effectiveness and sustainability of an energy conversion process.
What is the principle of the law of thermodynamics that states "useful energy in, useful energy out"?
The principle you are referring to is the second law of thermodynamics, which states that in any energy conversion process, some energy is lost as waste heat, resulting in a decrease in the overall usefulness of the energy.
What is a comparison of the amount of energy before conversion with the amount of useful energy after conversion?
The amount of energy before conversion is typically higher than the amount of useful energy after conversion due to energy losses during the conversion process. These losses can occur in various forms, such as heat, sound, or light, reducing the efficiency of the conversion process. It is essential to minimize these losses to optimize energy efficiency.
