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.

Understanding consequences of important physical properties of liquids
Liquid A is known to have a higher viscosity and higher vapor pressure than Liquid B.
Use these facts to predict the result of each experiment in the table below, if you can.
experiment
40.0 mL of Liquid A are put in one sealed
5 L flask, and 40.0 mL of Liquid B are put
in another sealed 5 L flask. The pressure in
each flask is then slowly lowered with a
vacuum pump.
A 250 mL beaker is submerged in a large
container of Liquid A and turned upside down,
and another 250 mL beaker is submerged
and turned upside down in a large container
of Liquid B. Hydrogen (H₂) s gas is bubbled
into each upside-down beaker until 100 mL
of liquid has been displaced. The masses m
and me of hydrogen inside each beaker is
then chemically determined.
Note for advanced students: you may assume
the solubility of H₂, in either liquid is very
low.
