Vocab Flashcards
Conduction
The vibratory movement of particles of matter transferring heat energy in solids
Chemical potential energy
Chemicals that aren’t moving
Convection
The transfer of heat energy in fluids by thermal currents of heated particles
Conversion
Transfers of energy
Electrical energy
Static flowing in machines
Elastic potential energy
Elastic not moving
Energy
The ability to do work
Liquid
The phase of matter that has an indefinite shape but a definite volume
Joule
Unit of energy
Kinetic energy
Energy in motion
Mass
The unit of weight
Mechanical energy
Energy made by machines
Gas
Indefinite shape and indefinite volume
Potential energy
Energy that is not in motion
Solid
Has a definite shape and a definite volume
Radiant energy
The transfer of heat energy
Radiation
The transfer of heat energy in the form of electrical energy
Heat and temperature
Temperature-kinetic energy of particles
Thermal energy- K.E of molecules or atoms
Heat- thermal energy that flows from temp. To lower temp.
Heat capacity
Specific heat capacity joules of heat needed to raise the temp of 1g of a substance
Water has a very high spec. Heat, so it heats up slowly and cools down slowly
If heat is absorbed by a substance Q is warmer
If heat is lost by a substance Q is negative
Phases of matter
Solid definite shape definite volume
Liquid definite volume no definite shape
Gas no definite shape or volume
Phase changes
When solids and liquids are heated, eventually they gain enough energy to overcome the bonds
During phase changes the temperature of the substance does not change
