What else can I help you with?
Entropy is the measure of disorder or unusable energy in a system true or false?
True. Entropy is a measure of the level of disorder or randomness in a system. It reflects the amount of energy that is not available to do work.
What does mechanical energy transform to?
A body with mass in motion possesses kinetic energy. If it is subject to friction, either on a rough surface or through the air, some of this energy will be converted to thermal energy, ie it will heat up. An extreme example of this is the re-entry of space vehicles into the atmosphere. It could also be converted to potential energy, such as when you fire a bullet upwards, it eventually stops rising, partly because of friction but also because it is being pulled back by gravity.
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).
What is the amount of available energy that can be used to promote change do work is called?
The amount of available energy that can be used to promote change and do work is called free energy. This is the energy that is available to do useful work in a system.
How is thermal energy measured in a system?
Thermal energy in a system is typically measured using a unit called the joule (J) or the calorie (cal). This measurement is based on the amount of heat energy present in the system.
Does the second Law of Thermodynamics contradict the First Law?
Not at all. The First Law states that energy is conserved - you can't create energy out of nothing, or make it disappear. The Second Law distinguishes usable from unusable energy, and states that the amount of unusable energy will increase over time - but the total (usable plus unusable energy) will still remain constant.Not at all.

What is the amount of energy which a system has to have in order for a chemical change to take place?
That is officially called the activation energy.
The amount of power derived from a device or system is its?
That amount is always less than the energy you put into the system. Divide the amount of useful energy you get from a system by the amount of energy you put into it, and you find the system's 'efficiency'.
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.
How is thermal energy measured in a system?
Thermal energy in a system is typically measured using a unit called the joule (J) or the calorie (cal). This measurement is based on the amount of heat energy present in the system.
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.
What is the difference between usable energy and total energy?
Usable energy refers to the energy that can be effectively converted and utilized for various purposes, while total energy represents the sum of all energy present within a system, including both usable and unusable forms. Usable energy can be harnessed to perform work, whereas total energy includes potential energy that may not be readily available for use.
What is a useful amount of energy you get from a system?
It is energy officenty
