 Temperature
Term
 Matter
Definition
 expands when temp increases and contracts when temp decreases.

Term
 The Celsius scale
Definition
 is used by most of the world, and it assigns a value of 0 to the temp at which water freezes and a temp of 100 to the temp at which water boils

Term
 Fahrenheit
Definition
 water freezes at 32 degrees and boils at 212 degrees
Term
 Fahrenheit:
Definition
 water freezes at 32 degrees and boils at 212 degrees
Term
 Kelvin scale
Definition
 ·         Its degrees are the same as the degrees on the Celsius scale with two notable differences:
Term
 Kelvin scale
Definition
 Its degrees are the same as the degrees on the Celsius scale with two notable differences
Term
 ·         The degrees are called "kelvins"   ·         The scale starts at 0 with the lowest possible temperature (AKA absolute zero), which is the temperature at which a substance has no more kinetic energy to release (this corresponds to -273 degrees Celsius).

Term
 ·         The temperature of something corresponds to the kinetic energy contained with the molecules of a substance.  It has to do with the average kinetic energy of all the molecules in that substance, which deals with the amount of molecular vibration within that substance.
Definition
Term
 average kinetic energy
Definition
 The temperature of something corresponds to the kinetic energy contained with the molecules of a substance. Molecules in that substance, which deals with the amount of molecular vibration within that substance.
Term
 That is why increasing temperature causes a substance to go from solid to liquid to gas - as the substance has greater and greater molecular vibration
Definition
Term
 Energy always transfers from the hotter substance to the colder substance
Definition
 ·         You touching a hot stove   ·         You touching a block of ice
Term
 heat
Definition
 The energy that transfers between objects of different temperatures is called
Term
 what does increasing temperature do?
Definition
 causes a substance to go from solid to liquid to gas - as the substance has greater and greater molecular vibration
Term
 Matter doesn’t contain heat
Definition
 ·         it lets off heat when it comes in contact with something that is a different temperature than it.
Term
