Science 2nd period final (CLOSED NOTEBOOK)

is the measurement of the average kinetic energy of a substance

Temperature

is the measurement of the total kinetic energy of a substance

Heat

is the amount of heat required to raise that temperature of one lb of H2O by one degree Fahrenheit

BTU

is absolute zero on the fahrenheit scale

-460 F

is equal to one therm

100,000 BTU

is the amount of heat required to raise the temperature of one gram of H2O one degree Celsius

one calorie

the ratio of substances heat capacity to that of H2O

specific heat

is the heat added to cause a change of state from a solid to a liquid

Latent heat of fushion

is the heat added to cause a change of state from a liquid to vapor

latent heat of vaporization

is the instantaneous change of state from a liquid to a vapor when pressure is reduced

flashing

is the heat transfer by the movement of air over a body

convection

is the heat transfer from the warm body to cooler surrounding surfaces

radiation loss

is the flow of heat from one object to another from direct contact with one another

conduction

is the heat change that can be detected by a thermometer

Heat

are excellent conductors of heat

solids

are poor conductors of heat

liquids

is the number or factor which shows the amount of expansion of a solid when heated one degree

coefficient of heat transmission

is the mechanical equivalent of heat

778 ft lbs

is steam in contact with the water from which it was formed

saturated steam

is steam which is heated above its corresponding saturation temperature

superheated steam
