Certainly! Let's break down each part of your question:
1.1 Define the following terms: 1.1.1 Solvent: A solvent is a substance in which another
substance (called a solute) is dissolved to form a solution. It is usually present in greater quantity
than the solute. 1.1.2 Matter: Matter is anything that has mass and occupies space.
1.2 Give an example of a heterogeneous mixture: An example of a heterogeneous mixture is a
salad, where different vegetables (lettuce, tomatoes, cucumbers) are mixed together but can be
distinguished from one another.
1.3 Identify 2 different ways of separating homogeneous mixtures: Two ways of separating
homogeneous mixtures are:
Filtration: Used to separate solids from liquids or gases using a filter medium that allows
the liquid or gas to pass through but retains the solid.
Distillation: Used to separate components of a liquid mixture based on differences in
boiling points.
1.4 State the three different states of matter: The three states of matter are:
Solid: Has a definite shape and volume.
Liquid: Has a definite volume but takes the shape of its container.
Gas: Takes both the shape and volume of its container.
1.5 Identify the process: 1.5.1 Change of state from liquid to solid: Freezing 1.5.2 Change of
state from gas to liquid: Condensation 1.5.3 Change of state from solid to gas: Sublimation
1.5.4 Change of state from liquid to gas: Evaporation 1.5.5 Change of state from gas to solid:
Deposition 1.5.6 Change of state from solid to liquid: Melting
1.6 Give 5 characteristics from the online study guide, of a good lesson plan: Five characteristics
of a good lesson plan typically include:
