QuestionAnswer
temperature Is a measure of the average kinetic energy of the individual particles in an object
Fahrenheit scale The temperature scale on which 32 and 212 are the temperature at which water freezes and boils
Celsius scale The temperature scale on which zero and 100 are the temperature at which water freezes and boils
Kelvin scale The temperature scale on which zero is the temperature at which no more energy can be removed from matter
absolute zero The temperature at which no more energy can be removed from matter
conduction The transfer of heat between particles within a substance
heat is transferred by conduction,convection,radiation
convection The moverment that transfer heat within the water
radiation Is the transfer of energy by electromagnetic waves
conductor A material that conducts tranfers heat between its particles
Insulator A material that dose not conduct heat well ex:wood,wool,straw,paper,and cork also gases, such as air are also good insulator
specific heat The amount of energy requried to raise the temperature of 1 kilogram of a substance by 1 kelvin
specific heat of common substance is Aluminum 903
specific heat of common substance is Brass 376
specific heat of common substance is Copper 385
specific heat of common substance is Glass 664
specific heat of common substance is Ice 2,060
specific heat of common substance is Iron 450
specific heat of common substance is Sand 670
specific heat of common substance is Silver 235
specific heat of common substance is Water 4,180
heat Is the movement of thermal energy from a substance at a higher temperature to another at a lower temperature
convection current A current caused by the rising of heated fluid and sinking of cooled fluid
the formula for change in energy mass x specific heat x change in temperature
solids the particles that make up a solid are packed close and cannot move out of position but can vibrate and they have a fixed shape and fixed volume
liquids particles are close but not as tight as in a solid and don't have a definite shape but they do have a fixed volume
gasses particles are moving so fast, they are not close and they expand to fit all available space. No fixed shape or volume
solid to liquid this change is called melting. More thermal energy=less rigidness in particles and more movement and the temperature at which this change occurs is its melting pot
liquid to solid this change of state is called freezing. A substance losses thermal energy.
liquid to gas this change in state is called vaporization. This liquid adsorb thermal energy and the particles escape the liquid and are now gas particles. Boiling- when vaporization takes place and leads to evaporation
gas to liquid this change in state is called condensation. This is when a gas loses thermal energy
thermal energy the total energy of the particles in an object.
thermal expansion is the expanding of matter when its heated
state solid, liquid and gas
change of state the physically change from one state of matter to another
meting the change of state from a solid to a liquid
melting point the temperature at which a substances melts
freezing point the temperature at which a substance freezes
vaporization the process by which matter changes from the liquid to the gas state
evaporation vaporization that occurs at the surface of a liquid
boiling vaporization that occurs on and below the surface of a liquid
boiling point the temperature that a liquid substances boils
condensation a change from the gas state to the liquid state
thermostat a device that regulates tempertaure
bimetallic strip a strip made of different metals that expand at different rates
