Heat was an invisible liquid.
The speed of the particles in a system.
It is a completely enclosed piston engine containing a working gas that is transferred back and forth between hot and cold heat exchangers.
The average kinetic energy of a systems atoms and molecules.
A dimensional unit
An instrument used to measure temperature
A property of mater to change predictability with a given temperature
A fixed, precisely known, and easily reproducible temperature value.
180 degrees between the freezing point of water and it's boiling point
Has 100 degrees between the freezing and boiling point of water
The temperature and pressure at which solid, liquid, and gaseous phases of a substance exist all at once
0 is where there is no energy in a substance and 273.15 is the freezing point of water
The distance between particles in a substance be come greater as temperature increases
The flow of thermal energy from one place to another
2nd law of thermal dynamics
The useful energy of a system tends to decrease and the entropy tends to increase
A measure of a systems disorder
Thermal energy moving from a warmer substance to a cooler substance
When the kinetic energy of two systems in the exact same
Thermal energy is carried from one location to anther by a fluid
The fluids cycle path
Electromagnetic energy moves in space
A material that resist the flow of thermal energy
The thermal energy in joules that an object must gain or lose to cause a temperature of 1 degree C
The heat capacity per gram of material
Measures the transfer of thermal energy between objects
Latent heat of fusion
The amount of thermal energy exchanged per gram of material during melting or freezing
Latent heat of vaporization
The amount of thermal energy exchanged per gram of material during the vaporization or condensing period
What did scientists believe about caloric?
They believed it was a liquid.
Who first successfully challenged the caloric theory?
