Why does the fusion of heavier atoms require higher temperatures than the fusion of hydrogen? a. Because of their greater mass, their gravitational attraction is stronger. b. Because of their greater positive charge, their Coulomb barrier is higher. c. Because of their greater magnetism, the collisions must be more violent. d. Because of their greater friction, overcoming viscosity is more difficult. e. None of these statements is true
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
