PHYSICAL SCIENCE - SPRING EXAM QUESTIONS AND VERIFIED

CORRECT ANSWERS GRADED A+




Kinetic Theory

An explanation of how the particles in gases behave

Melting Point

The temperature at which a solid becomes a liquid.

Heat of Fusion

The energy required to change a substance from a solid to liquid at its melting point.

Boiling Point

The temperature at which the pressure of the vapor in the liquid is equal to the external

pressure acting on the surface of the liquid

Heat of Vaporization

The amount of energy required for the liquid at its boiling point to become a gas

Sublimation

The process of a solid changing directly to a gas without forming a liquid.

Plasma

Matter that has enough energy to overcome not just the attractive forces between its

particles but also the attractive forces within its atoms

Thermal Expansion

Increase in the size of a substance when the temperature is increased.

Density

, Mass per unit volume of a material

Buoyancy

the ability of a fluid (liquid or gas) to exert an upward force on an object immersed in it

Pressure

Force exerted per unit area

Viscosity

The resistance of a fluid to flowing

Archimedes' Principle

The buoyant force on an object is equal to the weight of the fluid displaced by the object

Pascal's Principle

Pressure applied to a fluid is transmitted throughout the fluid

Bernoulli's Principle

Fluid velocity increases when the flow of fluid is restricted.

Temperature

A measure of the average kinetic energy of all the particles in an object.

Boyle's Law

If you decrease the volume of a container of gas and hold the temperature constant, the

pressure from the gas will increase.

Charle's Law

The volume of a gas increases with increasing temperature, as long as the pressure on

the gas does not change.

Substance

A type of matter with a fixed composition
