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.
Answer each of the following questions correctly(This is all about Chemistry Properties of Liquids and Intermolecular Forces).
Imagine that you take some water with a straw and put a few drops on plastic sheet and you move a drop around with your straw then you move one of the drops close to another one with your straw and lastly you put a small amount of one of the solids (salt, pepper, sugar, talcum powder)
on one of the drops.
a. What happens when two drops meet?
b. Complete the table below:
| Solids Added to the Drop | Changes the Drop's Shape ( Yes/No) |
