Science is considered as a continuous human effort to systemize knowledge to describe and understand nature. Chemistry is defined as that branch of science which deals with the study of composition structure and properties of matter and the changes which the matter undergoes under different condition and the laws which govern these changes. Chemistry- a key of mystery is a subject which is necessary for living in this world. Today chemistry has become a daily use in our life. Without chemistry

In particle physics‚ antimatter is material composed of antiparticles‚ which have the same mass as particles of ordinary matter but have opposite charge and other particle properties such as lepton and baryon number. Encounters between particles and antiparticles lead to the annihilation of both‚ giving rise to varying proportions of high-energy photons (gamma rays)‚ neutrinos‚ and lower-mass particle–antiparticle pairs. Setting aside the mass of any product neutrinos‚ which represent released energy

eventually there will only be microwave radiation as everything heads towards nothing. E=MC2; sum of all the energy in this universe=0‚ therefore sum all the mass should be zero as well. He further explains as to how for every matter there is anti matter and when matter meets anti matter microwave radiation is emitted. In other words the universe is heading towards a situation wherein eventually there would be only microwave radiation. The entire universe is moving in the direction of a puzzle trying to

Matter is anything that has a mass and takes up space. There are many ways to describe matter using physical and chemical properties. Physical properties are characteristics of a substance. Two types of physical properties are quantitative and qualitative. Quantitative is a property that has an amount or can be measured such as hardness‚ solubility‚ and viscosity. Qualitative is a physical description of matter such as color‚ clarity‚ and state. Chemical properties are characteristics of a substance
