It's a Law
What law tells us that energy can never be created or destroyed?
The 1st Law of Thermodynamics
Name the 3 ways heat is transferred
Radiation, Convection, and Conduction
A chemical process in which some material reacts quickly with oxygen to give off heat
Combustion
What is the temperature scale used in the United States - bonus What is boiling point and freezing point
Fahrenheit scale
Boiling point = 212 degrees
Freezing point = 32 degrees
What is an insulator
Something that does NOT transfer heat well
Which law says that when a substance reaches absolute zero (it reaches entropy) and it's molecules stop giving off heat and almost stop moving.
The 3rd Law of Thermodynamics
What is heat transfer by radiation?
Heat that travels through space
What 3 things does fire need
fuel, oxygen, heat
What does temperature measure
How active the molecules are
What is thermal expansion?
When things begin to heat up, they begin to expand.
Which law states that there is no transfer of heat between two objects in thermal equilibrium?
The Zeroth Law of Thermodynamics
What is conduction
Heat that travels THROUGH something by direct contact with something.
What is heat
Heat is the movement of molecules
What is the temperature scale used in most of the world outside of the United States?
Bonus - what is the boiling point and freezing point of water?
Celcius
Bonus - Boiling point = 100 degrees
Freezing point = 0 degrees
How do you measure temperature?
With a thermometer
Which law tells us that the universe as a whole is becoming less and less ordered and organized.
The 2nd Law of Thermodynamics
What is convection
Heat that travels WITH liquids and gases.
What is the temperature called that a substance must reach to ignite
Ignition temperature
What is the temperature used only by scientists
Kelvin
What is wonderful about water when it freezes
Unlike all other substance, it expands when it becomes a solid. This allows it to float and keep the animals alive.
