Summary Introduction
Introduction: “Energy cannot be created and destroyed, but it can be converted from one form to another”. It is the capacity to do work. It can tend to spread or disperse until no part of the system has more than one part.

Energy is defined as the ability to cause change. Which is the best reason why?
Because energy influences everything.
а.
b.
Because some form of energy is required to produce a change.
С.
Because energy is everywhere.
d.
Because energy can change forms.
Which of the following statements is a lie?
Select one:
a.
Chemical energy is the energy within chemical bonds. Energy is required for bonds to break while energy is released when bonds form.
b.
Exergonic chemical reactions release more energy than they absorb and the catabolism of the food in an energy bar serves as an example.
c.
The many forms of energy used up by cells comes from the breakdown of the chemical energy from the food we digest.
Which of the following statement(s) relating to energy is not true?
a. it is the capacity to do work or put matter into motionb. kinetic energy results from movement of charged particlesc. potential energy is stored in chemical bondsd. energy conversion is efficient as it loses heate. none of the above
