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.
(a)The pure liquid with the lowervapor pressure at room temperature has the ______ boiling point.
Vapor pressure :-
The pressure exerted by the vapour molecules on the surface of a liquid when both vapor and liquid are at equilibrium in a closed vessel at a particular temperature is known as vapor pressure .
Boiling point :-
The temperature at which vapor pressure of a liquid becomes equal to atmospheric pressure is known as boiling of that liquid
