Interpreting energy in chemistry, as it helps in working, heating objects, and in various other activities.
Every organism uses different types of energy to power the biological processes that help them grow and survive. Energy is nothing but a property of an object that can easily be passed from one thing to another either directly or by converting it into different forms. Though it can be transferred and changed, energy can neither be created nor destroyed.
Energy, derived from the Greek word “energia” for an operation or activity, is the capacity to do work. It can be transferred from one body to another, and exists in multiple forms, such as kinetic energy, potential energy, chemical energy, electrical energy, and more. The large extent of energy for life on earth is derived from the sun in the form of solar energy. The SI unit of energy is the joule (J). A joule is said to be consumed when one newton of force is applied to one meter of distance.
The energy possessed by any moving object by virtue of its motion is called kinetic energy, and can be calculated with the following equation.
KE = ½mv²
where m is the mass and v is the velocity of the moving object.
Examples of kinetic energy include things like blowing wind, birds flying, or a person riding a bike.
The moving object stores the energy due to its position relative to other objects, which is known as potential energy. PE = mxgxh, m is mass, g is the acceleration due to gravity, and h is height.
It is generally the sum of kinetic and potential energy.
M.E = (m x g x h) + (½mv²)
1. What is energy in science?
Energy is defined as the ability to do work. Energy can change its form but can neither be created nor destroyed.
2. Why is energy important in chemistry?
Energy is important in chemistry because it enables industrial chemical reactions to produce raw materials. And these raw materials are further used to make useful final goods like cars, bridges, etc.
3. What are the main uses of energy?
Uses of energy:
4. Why is the energy needed?
Energy is the basic need of a living organism. It is used to generate heat and light and produce several humans made things. Energy is used to improve and save various living organisms.
