Vocabulary flashcards covering key topics listed in Grade 10 Physics Page 1 notes.

Concerntration

A quantitative measure of the amount of solute dissolved in a given volume of solution.

Formula of concentration

C=n/V or C=m/MV

Percentage composition

The percentage by mass of each element contained within a chemical compound.

Formula for percentage composition

Element atomic mass ×Element no of atoms/ compound formula mass X 100

Empirical formula

The simplest chemical formula showing the lowest whole-number ratio of atoms of each element in a compound.

Molecular formula

A chemical formula that indicates the actual total number of atoms of each element present in a molecule of a compound.

Volume at STP

The molar volume occupied by one mole of any gas at standard temperature and pressure, equal to $22.4\,\text{dm}^3$.

Water crystallisation

Water molecules chemically bound within the crystalline structure of a hydrated salt.

Stoichiometry

The quantitative relationship between amounts of reactants and products in a balanced chemical reaction.

Percentage yield

The ratio of actual yield to theoretical yield expressed as a percentage: $\text{Percentage yield} = \frac{\text{Actual yield}}{\text{Theoretical yield}} \times 100\%$.

Vectors and Scalars

Vectors are physical quantities possessing both magnitude and direction, while scalars are physical quantities defined by magnitude only.

Example of a vector is

Example of scalars

Mechanics: kinematics

The subfield of mechanics that describes the motion of points, bodies, and systems without considering the forces that cause the motion.

Dynamics

The branch of mechanics concerned with the study of forces and their effects on motion.

Properties of scalars

Can be represented by magnitude only

Properties of a vector

Represented with magnitude and direction
