) What is the definition of conduction? *
1 point
When heat is transferred (moved) from objects like rays of light or waves in a microwave oven.
When heat is transferred (moved) from objects that are touching.
When heat transfers (moves) through a heater in your house.
A liquid that becomes more dense (compact) as it rises and the molecules slow down so the liquid sinks.
2) Warm air is dense than cold air and rises creating convection currents. *

When heat transfers (moves) through waves.
When heat transfers from objects that are touching.
Heat traveling from the sun.
Movement in a gas or liquid where the warmer parts (fast moving molecules) move up and the colder parts (slower moving molecules) sink.

8) Use the image below from our Conduction lab and pick the response that BEST explains WHY the metal spoon is a better conductor of heat. *

There are fewer particles (atoms, molecules, and free electrons) in the metal spoon than the plastic knife and wooden chop stick so heat travels faster from the boiling water into the metal spoon.
There is the same amount of particles (atoms, molecules, and free electrons) in the metal spoon than the plastic knife and wooden chop stick so heat travels faster from the boiling water into the metal spoon.
There are more particles (atoms, molecules, and free electrons) in the metal spoon than the plastic knife and wooden chop stick so heat travels faster from the boiling water into the metal spoon.

9-a) Third Grader in Pain Over their Day in the Sun
Did you ever hear that NOT following your parents advice can be painful? In this story, a girl named Sue decided that she didn't need to listen to her parents while playing at the beach. Sue is a young star surfer and had a HUGE surfing competition in Narraganset. She was the youngest surfer to ever enter the teenage competition. Before she set out to surf, her proud parents told her to make sure to put on WATER PROOF suntan lotion. Sue smiled and said, "Of course I will, don't be silly." As luck would have it, Sue didn't read the label on the suntan bottle and used lotion that was NOT waterproof. Later that night after celebrating her HUGE VICTORY (she beat out every teenager at the event) a friend patted her on the back. Sue screamed, "OUCH"
10) The image BELOW shows a convection current. Which description most accurately describes this process. *
1 point
Convection currents is the circular motion that happens when cold air or liquid, which has faster moving molecules, makes it less dense and rises, while the warm air or liquid slows down the molecules causing the air or liquid to sink.
Convection currents is the circular motion that happens when molecules move at the same speed the entire time.
Convection currents is what happens when water does NOT move.
Convection currents is the circular motion that happens when warm air or liquid, which has faster moving molecules, makes it less dense and rises, while the cool air or liquid slows down the molecules causing the air or liquid to sink.
