, QUESTION 1

1.1.1

A solvent is a substance capable of dissolving another substance to form a
solution. It is typically a liquid, but can also be a solid or gas. Solvents are
commonly used in various processes such as cleaning, chemical reactions, and
in the manufacturing of products such as paints and pharmaceuticals.



1.1.2

Matter is anything that has mass and takes up space. It is the material
substance that makes up the physical universe, including everything from
atoms and molecules to larger objects like planets and stars. Matter can exist
in various states, such as solid, liquid, gas, and plasma.



1.2.

A heterogeneous mixture is a combination of two or more substances that are
not uniformly distributed and can be easily distinguished. The components of a
heterogeneous mixture do not blend together on a molecular level.

An example of a heterogeneous mixture is a salad. A salad is made up of
different ingredients such as lettuce, tomatoes, cucumbers, and onions. Each
of these ingredients retains its own properties and can be easily distinguished
in the mixture.

Another example is a bowl of cereal with milk. The cereal and milk do not mix
completely, and the different components can be seen and separated from each
other.



1.3.

Filtration: This method involves using a porous barrier, such as filter paper or a
sieve, to separate particles of different sizes in a mixture. The smaller particles
pass through the barrier, while the larger particles are left behind.
