A measure of how hot or cold something is compared to a reference point
Temperature
Materials that do not conduct heat well
Insulators
Which law of motion is Force equals mass times acceleration
2nd
Expanding of matter when it is heated
Thermal Expansion
True or False: our weight is different on the Moon as it is on Earth
True
The lowest temperature possible, when particles have no kinetic energy
What temperature does water boil and freeze on the Fahrenheit Scale
212 and 32
Who discovered the 3 laws of motion
Sir Isaac Newton
Freezing and Boiling Point of water in Celsius
0 and 100
A force that pulls object toward each other
Gravity
The transfer of thermal energy from a warmer object to a cooler object
Heat
Only form of heat transfer that does not require matter. Heat is transferred by electromagnetic waves
Radiation
What is the SI unit for measuring Force
Newton
True or False: A one degree change in Fahrenheit is greater than a one degree change in Celsius
False (other way around)
What is the first law of motion
An object at rest will stay at rest unless acted upon by a non-zero net force
Type of heat transfer that occurs only in fluids
Convection
Heat transfer from one particle of matter to another within an object or between two objects
Conduction
An example of this type of friction is a bird flying through the sky
Fluid Friction
Which has more thermal energy a life-sized igloo or a small candle
Igloo
If the force of an object is 15 and the mass is 3, what is the object's acceleration
5
Movement of fluid caused by differences in temperature, that transfers heat from one part of fluid to another
Convection Current

Specific Heat
What is the 3rd law of motion
For every action there is an equal but opposite reaction
The freezing and boiling point of water in Kelvin
273 and 373
What unit is heat measured in
