Term
The tempature -
Definition
increases then particles average speed also increase in random motion.
Term
define: tempature-
Definition
is a measure of the average kinetic energy of the particles in the object.
Term
SI unit for tempature is:
Definition
Kelvin
Term
Matter is made:
Definition
of tiny particles called atoms and molecules.
Term
1 Celsius degree is the same as 
Definition
 1 Kelvin degree
Term
The sum of the Kinetic energyand Potential energy:
Definition
of all particels in an object is the Thermal Energy of the object.
Term
If the tempature doesnt change:
Definition
the thermalenergy that flows from something at a higher tempature substance, as well as the amount of heat that is added.
Term
heat equals-
Definition
Joules(J)
Term
Heat:
Definition
is the thermal energy that flows from something at a higher tempature to something to a lower tempature.
Term
Specific Heat:
Definition
the amount of heat that is needed to raise the tempature of 1 kg of some material by 1 Celsius.
Term
Equation for heat:
Definition

mass x change in tempature x specific heat

 

Q=m(Tf-Ti)*C

          

Term
unit for specific heat:
Definition
[J/(kg*C)]
Term
Conduction:
Definition
is the transfer of thermal energy by collisionsbetween particles in matter.
Term
Three different types of heat production:
Definition
Convection, Conduction, and Radiation
