Fred is boiling water on a stove. When he touces the handle of the pot, he notices it is hot. What is most likely the reason the handle is hot? (radiation, conduction convection, or transpiration)
What is conduction.
100
How does heat energy from the sun reach Earth? (conduction, convection, insulation, radiation)
What is radiation.
100
Which best describes how heat is transferred? (heat only flows within individual substances; heat flows from a warmer substance to a cooler substance; heat flows from a cooler substance to a warmer substance; heat flows in many different directions between substances)
What is heat flows from a warmer substance to a cooler substance.

Jack is wearing gloves while he gets a hot pan out of the oven. Which best explains why Jake needs to wear gloves while he is carrying the hot pan? (gloves proect his hand from convection heat, radiated heat, conducted heat, surrounding air)
What is conducted heat.
200
Joe wants to slide down on a sunny day, but the slide is too hot. Which is most likely the raso for the slide being hot? (radiation from the sun, convection from the sun, conduction from the sun, traspiratin from the sun)
What is radiation from the sun.

The heat from a lamp allows a lizard to remain warm. This is an example of which type of heat transfer? (radiation, convection, conduction)
What is radiation.

Jackson likes to cook but is always in a hurry. He needs a pot that will cook his food quickly. Which is the best material for his cooking pot? (copper, glass, plastic, wood)
What is copper.
300
Dylan will be hiking on a sunny day. What type of container should he store his water in if he wants it to stay cool? (a metal bottle, becuase metal radiates heat; a metal bottle because metal easily conducts heat; a thick plastic bottle, because plastic conducts heat; a thick bottle, because plastic does not easily conduct heat)
What is a thick plastic bottle, because plastic does not easily conduct heat.

Mrs. Roth's class is learning about heat transfer. Her class observes a pot of boiling water and describes the process. The sutdents note that as the water at the bottom heats up, it rises. The cool water at the top falls, and the cycle continues. Which best describes the process the students are observing? (conduction, convection, transformation)
What is convection.
400
Which best describes what will happen to water when it is heated above its boiling point? (double in mass, it will turn into a solid, it will turn into steam)
What is steam.
400
Which organism most directly converts the sun's radiation into energy it can use? (grass, snake, human, mushroom)
What is grass.
400
Which best describes how heat changes the state of a substance? (heat destroys the molecules in a substance; heat absorbs the molecules of a substance and releases them once they cool; heat causes the molecules of a substance to spread out into a new arrangement)
Why does heat cause the molecules of a subtance to spread out into a new arrangement?
500
Which best explains why a wooden spoon can be used to stir hot soup on the stove? (wood is a good conductor of heat and transfers energy to the spoon, Wood is a poor conductor of heat and transfer energy to the spoon, wood is a poor conductor of heat and does not allow the transfer of energy to the spoon)
What is a poor conductor of heat and does not allow the transfer of energy to the spoon - wood.
500
Rays from the sun are shining down on a house. What effect does the sun have on the temperature of the house? (the temp. of the house increases because heat radiates from the sun; the temp. of the house increases because heat is conducted by the sun; the temp. of the house decreases because heat is convected by the sun)
What is the temp. of the house increases because heat radiates from the sun.
500
Which is an example of heat being transferred by conduction? (a furnace heating the air in a school; an ice cube melting in a person's hand; a pot of water on a stove boiling; the sun heating water in a swimming pool)
Why an ice cube melting in a person's hand?
