When a volatile liquid is completely vaporized in an Erlenmeyer flask, the volume of the flask (and thus the vapor) can be determined by one of two methods. One method is by filling up the whole flask with water and then finding out the water volume by pouring the water into a measuring cylinder over multiple times and read off its volume. ● From the topics we learnt this semester, what do you think can be the other method of determining the volume of water in the flask?
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.
