Term
 Industrial revolution
Definition
 Revolution that started in 18th century, with the invention of the steam engine.
Term
 Steam Engines
Definition
 Used to power trains, factories and water pumps for coal mines
Term
 Thermodynamics
Definition
 Heat transformations and motion of atoms
Term
 Engineers
Definition
 use law of thermodynamics to develop new inventions, like engines, refrigerators, and other machines.
Term
 Conduction
Definition
 the transfer of kinetic energy when particles collide
Term
 Thermal Equilibrium
Definition
 the state in which the rate of energy flow between two objects is equal and the objects are at the same temperature.
Term
 Heat
Definition
 Energy transferred between two objects in contact with one another and always flows from the hotter object to the cooler object.
Term
 Convection
Definition
 A type of thermal energy transfer that occurs from the motion of fluid in liquid or gas that is caused by differences in temperature.
Term
Definition
 The thermal transfer of energy by electromagnetic waves through the vacuum of space.
Term
 Specific Heat
Definition
 The amount of energy that must be added to a material to raise the temperature of a unit mass by one temperature unit; is measured in J/kg*K
Term
 Heat of fusion
Definition
 The amount of heat required to change 1 kg of substance from a solid state to a liquid state at its melting point.
Term
 Heat of Vaporization
Definition
 The amount of heat required to change 1 kg of a substance from a liquid state to a gaseous state at its boiling point.
Term
 First Law of Thermodynamics
Definition
 States that the change in thermal energy of an object is equal to the heat that is added to the object, minus the work done by the object.
Term
 Second Law of Thermodynamics
Definition
 States that natural processes go in a direction that maintains or increases the total entropy of the universe.
Term
 Heat Engine
Definition
 A device that continuously converts thermal energy to mechanical energy; requires a high-temperature thermal energy source, a low-temperature receptacle (a sink), and a way to convert the thermal energy into work.
Term
 Etymology of Seahawks
Definition
 The name Seattle Seahawks ("Seahawk", another name for osprey) was selected on June 17, 1975 after a public naming contest which drew more than 20,000 entries and over 1,700 different names. The name "Seahawks" was submitted by 151 entrants, and Mary Hoolahan of Seattle, WA was selected the winner. The name originated from the Peninsula Highschool in Gig Harbor.
Term
 Entropy
Definition
 A measure of disorder in a system
Term
 Equilibrium
Definition
 The condition in which the net force on an object is zero
Term
 Thermometer
Definition
 A device that measures the temperature of an object.
Term
 Temperature
Definition
 the degree or intensity of heat present in a substance or object
Term
 Celsius
Definition
 a scale of temperature in which water freezes at 0° and boils at 100° under standard conditions.
Term
 Kelvin
Definition
 the SI base unit of thermodynamic temperature, equal in magnitude to the degree Celsius, and where zero is absolute zero, the coldest temperature possible.
Term
 Calorometer
Definition
 A device used to measure changes in thermal energy
Term
 Heat Transfer
Definition
 Q=mCΔT
Term
 Melting Point
Definition
 The point where a substance changes from a solid to a liquid.
Term
 Boiling Point
Definition
 The point where a substance changes from a liquid to a gas.
Term
 Change of State
Definition
 When the thermal energy of a substance changes, so that the the properties of it changes from a either gas, liquid, or solid, to another form.
Term
 Refrigerator
Definition
 Uses mechanical work to remove thermal energy from an object.
Term
 Heat Pump
Definition
 A refrigerator that can be run in two directions, both in and out. It always uses mechanical energy to transfer heat fro ma cold object to a warmer one.
