Matter in Our Surroundings

The universe is made up of matter and energy. While the transformation of matter to energy can be seen, the transformation of energy to matter cannot be seen. In order to know more about the interrelationships and the proper utilization of energy for the benefit of mankind. and to know the world around us, we need to know about the matter in detail. Matter exists on the earth even before the first man had appeared on it. The matter from which a thing is made is called material.

The first thing to understand about matter is that not all of it can be seen directly, and not everything we see around is matter. So explain what is matter? Or matter definition There are several criteria that must be satisfied before an entity can be described as matter. First it must occupy space. Matter has mass. Mass is defined as the amount of matter in an object but it should not be confused with weight. Matter is therefore anything that can be weighed, pushed, pulled, have its slape changed and so on.

Dalton’s Atomic Theory Explanation

Dalton ‘s theory of atomics was based on chemical composition laws. According to the atomic theory of Dalton any molecule consists of small particles called atoms, each of which has a fixed mass. It also states that atoms of different elements combine to form compounds and that each element ‘s number and amount of atoms in a compound are set. Now since the number of atoms is a given combination, the form of atoms and the mass of atoms of each element is fixed, so a combination would still have the same elements mixed by mass in the same proportions.

One of the main disadvantages to Dalton’s theory to atomic matter was that it was thought that atoms were indivisible. We realise the atoms can be further separated into still smaller particles called electrons, protons and neutrons under certain circumstances. Therefore atoms are composed of three particles themselves; electrons, protons , and neutrons. Dalton’s atomic theory states all of an element’s atoms have almost the same mass. The atoms of the same substance can now be found to have slightly different masses. Dalton ‘s theory of atomics claimed atoms of different elements had different weights.

Matter and Energy

Matter and energy is about a particle and how it interrelates with all physical matter. It is a one-particle theory of matter, energy, and the Universe “the Ultimate Mass Particle”. Matter can be transformed into energy. The energy doesn’t just appear from nowhere. It is actually matter changed to a different form.

Einstein also discovered that high levels of energy can add to an object’s mass. As an object accelerates toward the speed of light, gaining energy as it does, it becomes more and more massive. So modern science no longer identifies separate laws of conservation of energy and conservation of mass. Instead there is one law – the law of conservation of mass energy.
