What is specific heat?
the exactness of heating up an object or changing the state of an object
What is thermal expansion?
liquids expand when heated
What is a Thermometric property?

What is the Kelvin scale based off of?
thermal energy or entropy. absolute zero = no entropy = no thermal energy
What are the 3 ways that heat is transferred? describe them
conduction - warm and cold objects contact each other until the temperature evens out.
convection - the flow of thermal energy as fluids
Radiation - moves in the form of electromagnetic waves
What 2 factors do thermal energy depend on?
Temperature and size
