Energy is a force required for any type of motion.
W = F x D
-the ability to do work.
Define Boiling Point.
Boiling Point is the temperature change of a Liquid to a Gas.
Define Freezing Point.
Freezing Point is when all the heat is removed causing the water to change from a liquid to a solid.
Define Fluid.
Fluid is anything that will flow. Includes all Liquids and Gases.
Define Condensation Point.
Condensation Point is the change of a Gas to a Liquid.
Describe what causes air pressure.
Heat causes the increase in pressure, and with the increase of pressure comes the increase of heat.
Define Nuclear Energy.
Nuclear Energy is energy stored in the nucleus of atoms.
The 3 different Temperature scales are:
1.Fahrenheit
2. Celsius
3.Kelvin Scale of Absolute
Fahrenheit:
Freezing point is 32*F.
Boiling point is 212*F.
F=180/100*C + 32*
The formula for Mechanical Energy is:
KE = 1/2MV(Squared)
Define Atoms.
Atoms are the smallest particles of an Element.
Define Compound.
Compunds are the purest substance that is made up of 2 or more different Elements.
Celsius:
Freezing point is 0*C
Boiling point is 100*C.
Define Radiation.
Radiation is infra-red.
Define Calorie.
Calorie is the amount of heat needed to change the temperature of 1 gram of water to 1 degree Celsius.
1 Calorie = 4.2 joules
Define Matter.
Anything that occupies space.
Define Latent Heat of Vaporization.
Latent Heat of Vaporization the amount of heat needed to change Liquid water to Gas or Gas to Liquid. Latent Heat of Vaporization shows up as Potential Energy not Kinetic Energy.
What determines whether something is a Liquid, a Solid, or a Gas.
Temperature alone determines whether something is a Solid, a Liquid, or a Gas.
The only 2 entities of the universe are:
Units of Energy and Matter.
Explain how Steam is so much hotter than water at the same temperature.
Changing 1 gram of water to Steam requires an extra 540 calories/grams of Energy to raise the temperature 1 degree Celsius.
Define Latent Heat of Fusion.
Latent Heat of Fusion is the amount of heat needed to change 1 gram of liquid to a solid or vice versa.
Lf = 80 calories/gram
Define Pressure.
Pressure is the pounding of molecules against anither force.
Define Sublimination.
Sublimination is changing directly from a solid to a gas, and vice versa.
Define Elements.
Elements are the purest form substance that cannot be broken down into a simplier solution.
Define E = mc2.
E = mc2 +Energy is mass(kg) x speed of light(m/sec.) x speed of light(m/sec.)
Energy is measured in "joules".
Define Wind Velocity.
Determines the destruction of the Potential Energy from the heat and moisture.
The general structure of Matter is:
Carbon and Carbon matter.
Define Heat and Temperature.
Heat is total motion (KE). Temperature is the average speed, and is measured in Fahrenheit, Celsius, and by the Kelvin Scale. The temperature of a body rises as heat is added only when the substance is not undergoing a change in phase.
Describe Energy and how it is measured.
Energy is described as having no Mass, that it cannot be measured directly, is measured by the effect on matter.
Define Nucleus.
Nucleus is all the weight of the Atom.
Define Neutrons.
Neutrons are "neutral" electrically charged.
Define Molecule.
Molecules are the smallest particles of a compound.
Kelvin Scale:
Freezing point is 273*
Boiling point is 373*
2nd Law of ThermoDynamics states:
that heat flows from high temperatures to low temperatures (temperature determines the flow of heat).
Define Electron Cloud.
Electron Cloud is all the space or volume of the Atom.
Define Protrons.
Protrons are positively charged (+).
Nucleus carries:
Electrons that are "electrically" charged.
Law of Conservation states:
that matter cannot be created nor destroyed.
Protrons determine what?
The number of Protrons determines the Elements an Atom belongs to.
Define Gases.
Gases have no definite shape or volume. Molecules collide and move away at high speeds.
The 3 Fundamentals of Nature are:
1.Gravity-always pulls
2.Electrodemagnetic Force- push or pull (magnets +/-).
3.Nuclear Force-attracts-in extremely short distance (velcro).
Central Dogma in Science is:
that there shall be no Dogma in science.
Law of Conservation states:
that Energy cannot be created nor destroyed. It is measured in "joules".
Electrons are:
Protrons nad Neutrons.
Define Dogma.
Dogma is the unquestioned belief or idea.
Define Specific Heat and it's formula.
Specific Heat is the amount of heat needed to change the temperature of one gram of a given substance 1 degree Celsius.
H = MC x(Delta change)Temperature
Define Dietetic Calorie.
The Dietetic Calorie is 1 kilo-calorie = 1,000 calories.
Define Surface Tension.
Surface Tension are the molecules at the surface that stick together, but are free to migrate.
The 3 states of Matter are:
1.Solids
2.Liquids
3.Gases
The 3 ways heat is transferred are:
1.Conduction
2.Convection
3.Radiation
Define Theory.
Theory is that something has been proven in many different ways in life. It requires proof and is always up to questioning.
Define Potential Energy.
Potential Energy is stored - any form can be Potential E.
True/False
Atoms are made exactly the same.
True.
Define Convection.
Convection is that warmer fluids rise.
Define Conduction.
Conduction is the transfer of heat.
Define Kinectic Energy.
Kinectic Energy is energy of motion or in motion.
What measures the average speed of molecules?
Temperature measures the average speed of molecules.
Kinestic Theory of Matter states:
1.All matter is made of timy particles called Molecules.
2.Milecules are in constant motion.
3.Molecules do not lose energy in collision.
Define Liquid.
