Heat

transfer energy from one object to another because of a temperature difference

Temperature

is a measure of how hot or cold an object is

Absolute Zero

a temperature of 0 kelvins

Thermal Expansion

increase in volume of a material due a temperature increase

Specific Heat

amount of heat need to raise the temperature

Calorimeter

an instrument used to measure changes in thermal energy

In the 1700s heat was known as?

 caloric

Benjamin Thompson was also know as

count rumford

In what direction does heat flow spontaneously

from hot objects to cold

 What  does thermal energy depend on

Mass temperature and phase

How is heat measured

joules or calories

How much energy is needed to rasie the temperature of one gram of water one degree celsius?

one calorie

How many joules is one calorie 

4.184

The unit for specific heat is

joules per garm per degree clesius

or

j/g* c

Formula for specific heat

Q=m*c*t

(heat= mass * specific * change in temperature)

What principle does a caorimeter use

heat flows from a hotter object to a colder until both reach the same temp

particles of matter tend to move father apart as temp rises
