Why do sidewalks and driveways have separators in them?
So they are easier to remove and repair
To allow them to expand in summer and contract in winter without cracking
To save on the cost for concrete when pouring over large surfaces
The gaps allow heat from below the ground to rise up and melt ice and snow in the winter
Sand on the beach is hotter than water in the lake because it takes less energy for the sun to heat it. Sand has a lower ____________ than water

Molecules do THIS when they heat up
Move faster
Move closer together
Get larger
All of the above
A golfer hits a ball across a green, and it stops JUST BEFORE it went in the hole. Why did it stop moving?
It ran out of energy
A constant force was necessary to keep it moving across the green
Friction caused it's mechanical energy to turn into heat energy
The force of gravity balanced out with the putter's force which cancelled out the ball's motion
Which temperature scale uses Absolute Zero as its standard?
Fahrenheit
Celsius
Kelvin

Mr. Johnson's cheap cooler only kept his soda cold for 6 hours (before all the ice melted). Why?
The heat energy inside the cooler went to the outside
The coldness escaped to the outside of the cooler
The heat energy outside the cooler went to the inside
Plastic is a poor insulator of heat energy
Mrs. Johnson got him a Yeti cooler for Valentine's Day- which keeps soda cold ALL WEEKEND! Why does it work better?
It is a much better conductor of heat energy
It prevents air molecules from getting inside the cooler
It stops the motion of molecules inside the cooler
It is better insulated to prevent heat energy from getting inside
What Law states that energy can't be CREATED or DESTROYED, but it can be CHANGED?
Kinetic Law of Matter
Law of Conservation of Energy
Law of Gravity
Law of Equivalent Energy
