FOSS Chemical Interactions - Final Review FULL VERSION

Front

What is compression in the context of gases?

Back

Compression is the process of reducing the volume of a gas by applying pressure, causing the gas particles to move closer together.

Front

Who first organized the Periodic Table and based it on what property?

Back

Dmitri Mendeleyev first organized the Periodic Table based on the mass of the elements.

Front

How do cold air particles differ from hot air particles?

Back

Cold air particles are closer together, have less kinetic energy, and move slower than hot air particles.

Front

What does the Law of Conservation of Matter/Mass state?

Back

The Law of Conservation of Matter states that matter cannot be created or destroyed in a chemical reaction; it only changes forms.

Front

What are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction, found on the left side of the equation.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What is kinetic energy (KE) in relation to particles?

Back

Kinetic energy is the energy that particles possess due to their motion; higher temperatures mean higher kinetic energy.

Front

What is the significance of the Periodic Table in chemistry?

Back

The Periodic Table organizes elements based on their properties and atomic structure, helping predict chemical behavior.

Front

What happens to gas particles when they are heated?

Back

When gas particles are heated, they gain kinetic energy, move faster, and spread apart, causing the gas to expand.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
