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
