Physical Science Unit 3 Review

States that the temperature and volume of a gas are related such that if the pressure is constant, an increase in temperature will produce a proportionate increase in the volume.

• Newtons Law

• Boyle's Law

• Charles Law

• Law of conservation of mass

A substances internal resistance to flow.

• Momentum

• Flow

• Inertia

• Viscosity

States that the volume and pressure of a gas are related, such that if the temperature of a gas remains constant, an increase in volume causes a proportional decrease in the pressure.  (As volume goes up, pressure goes down)

• Kelvin's Law

• Bolye's Law

• Charles Law

• Newtons Law

The ability of a fluid, which include liquids and gases, to exert an upward force on an object immersed in it.

• Floaties

• Newtons 1st Law

• Thermal expansion

• Bouyancy

Amount of energy required to change a substance from the solid phase to the liquid phase

• Newtons 1st Law

• Buoyancy

• Sublimation

• Heat of fusion

Element or compound that cannot be broken down into simpler components without losing the properties of the original substance.

• Substance

• Element

• Compound

• Molecule

Substance with atoms that are all alike and cannot be broken down into simpler substances.

• Substance

• Element

• Compund

• Molecule

Substance in which two or more elements are combined in a fixed proportion

• Subtance

• Molecule

• Compound

• Element

A mixture that does not have a uniform composition and in which the individual substances remain distinct. (ex: oil & water, italian dressing, trail mix, cereal with milk)

• Heterogeneous Mixture

• Synthesis mixture

• Homogeneous Mixture

• Pure mixture

A mixture that has a uniform composition throughout and always has a single phase, also called a solution. (ex: cake batter, kool aid, coffee with cream, salt water)
