Our first topic is ENERGY!!
Energy is essential for life. It provide us motion, fuel, light and many others!
But what is the exactly definition of energy?
Well, some say that energy is the strength necessary to sustain our physical and mental activities. Others, will say is the ability to do work.
However, in this course let's think energy as a amount of power. Power that is essential for life.
There are many forms of energy! Energy of motion, light energy, molecular energy, sound energy, nuclear energy and etc.
It is very important to know that energy originate from the sun!
Yes, the sun. Our biggest star is bale to convert hydrogen atoms into helium atoms, providing a enormous amount of energy to the earth.
This energy is converted into chemical energy into the plants by a process called Photosynthesis. This chemical energy is essential for plants to carry its metabolic life.
When animals eat the plants, this energy will now help the new organism to live its metabolic life. And it goes on and on.
When plants or animals consume energy, it is stored in the chemical bonds. When the plant and animal decompose, chemical reaction occur, since bonds are been broken. The energy can either be released or absorbed.
But how sun does not give nuclear energy for example. So how do they all originate there?
Well, to answer this question we have to understand the root of chemistry known as Thermochemistry.
In thermochemistry we study some laws called the laws of conservation of energy.
The first law explains that energy is never created or destroyed, however it is always transformed.
Energy originates from the sun in form of life, however it transforms into all the types of energy we know of.
In chemistry, energy is essential for chemical reactions to happen. Remember this: Bonds to be broken of formed, require energy.
