Heat Transfer
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.
Conduction
A viscous liquid derived from petroleum, especially for use as a fuel or lubricant.
Oil
Define melting.
to make or become liquefied by heat
A branch of science that deals with living organisms and life processes.
Life science
An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
1st law
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 the transfer of heat.
Convection
Relating to or denoting the generation of electricity using flowing water to drive a turbine that powers a generator.
Hydroelectricity
Define freezing.
process through which a substance changes from a liquid to a solid
The branch of science dealing with the physical constitution of the earth and its atmosphere.
Earth science
Acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
2nd law
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
Radiation
Flammable gas, consisting largely of methane and other hydrocarbons, occurring naturally underground and used as fuel.
Natural gas
Define condensation.
water that collects as droplets on a cold surface when humid air is in contact with it
The sciences concerned with the study of inanimate natural objects, including physics, chemistry, astronomy, and related subjects.
Physical science
For every action, there is an equal and opposite reaction.
3rd law
What is an example of conduction?
Warm your back muscles with a heating pad.
A colorless, odorless, highly flammable gas, the chemical element of atomic number 1.
Hydrogen
Define vaporization.
process that occurs when a chemical or element is converted from a liquid or a solid to a gas
Examples of Life science.
turtle, cat, quail
What is an example of the 1st law of motion?
A box won't move unless a force is acted upon it.
What is an example of convection?
boiling water
A combustible black or dark brown rock consisting mainly of carbonized plant matter found mainly in underground deposits and widely used as fuel.
Coal
Define sublimation.
chemical process where a solid turns into a gas without going through a liquid stage
Examples of Earth science.
bees, mold, rainwater
What is an example of the 2nd law of motion?
If you use the same force on a truck and a car the car will go farther because it has less mass.
