d) Plasma

the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
a) Heat
b) Energy
c) Specific Heat
d) Temperature

a result stating that a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.
a) Radiation
b) Archimedes” Principle
c) Floating
d) Convection

the temperature at which a given solid will melt.
a) Boiling Point
b) Freezing Point
c) Melting Point
d) Hot Point

the principle in hydrodynamics that an increase in the velocity of a stream of fluid results in a decrease in pressure. Also called Bernoulli effect or Bernoulli theorem.
a) Newton's Laws
b) Aristotle
c) Thermal Energy
d) Bernoulli’s Principle

the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
a) Convection
b) Conduction
c) Radiation
d) Thermal Energy

heat seen as a form of energy arising from the random motion of the molecules of bodies, which may be transferred by conduction, convection, or radiation.
a) Heat
b) Convection
c) Thermal Energy
d) Conduction

a substance that flows freely but is of constant volume, having a consistency like that of water or oil.
a) Gas
b) Liquid
c) Solid
d) Plasma

the ability or tendency to float in water or air or some other fluid.
a) Floating
b) Sinking
c) Buoyancy
d) Solid

the degree of compactness of a substance.
a) Density
b) Thermal Energy
c) Mass
d) Weight

a substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape (unlike a solid) and no fixed volume (unlike a liquid).
a) Gas
b) Solid
c) Liquid
d) Plasma

the lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal. It is zero on the Kelvin scale, equivalent to –273.15°C or –459.67°F.
a) Freezing
b) Absolute Zero
c) Melting
d) Cooling

continuous physical force exerted on or against an object by something in contact with it.
a) Thermal Energy
b) Melting Point
c) Pressure
d) Liquid

the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
a) Thermal Energy
b) Temperature
c) Heat
d) Energy

physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.
a) Gas
b) Solid
c) Liquid
d) Matter

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
a) Convection
b) Conduction
c) Radiation
d) Thermal Energy

the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
a) Convection
b) Conduction
c) Radiation
d) Thermal Energy
