Question 1
1.
Which is correct about the innitial (beginning) temperature of the blocks?
Metal block feels colder because it is colder.
Plastic block feels warmer because it is warmer.
Metal feels colder and the plastic feels warmer but they are the same temperature.
Question 2
2.
Which is correct statement describing ice melting?
Metal block melts faster because it transfered energy to the ice making the water molecules slow down.
Metal block melts faster because it transfered energy to the ice making the water molecules speed up.
Plastic block melts faster because it transfered energy to the ice making the water molecules slow down.
Plastic block melts faster because it transfered energy to the ice making the water molecules speed up.
Question 3
3.
Which is correct about the final (ending) temperature of the blocks after the ice melted?
If the metal block gets colder, now the metal molecules are moving faster.
If the metal block gets colder, now the metal molecules are moving slower.
Temperature has no affect on molecule speed.
Question 4
4.
In the above picture. Descirbe the energy flow.
Energy is moving from the
ice to the tile
and meliting the ice.
Energy is moving from the
tile to the ice
and melting the ice.
Question 5
5.
In the above picture. Descirbe the energy flow.
The ice is endothermic and the tile is endothermic.
The ice is endothermic and the tile is exothermic.
The ice is exothermic and the tile is endothermic.
The ice is exothermic and the tile is exothermic.
Question 6
6.
In the above picture. Desccribe the motion of the molecules.
Tile is speeding up and so is the water.
Tile is speeding up and the water is slowing down.
Tile is slowing down and so is the water.
Tile is slowing down and the water is speeding up.
Question 7
7.
The book feels warmer and the metal feels colder. Which is the correct statement below?
The book feels warmer because it is
conducting heat to your hand
.
The metal feels colder because it is
conducting heat from your hand.
Question 8
8.
The book feels warmer and the metal feels colder. Which is the correct statement below?
The book feels warmer because it is
insulating heat from leaving your hand
.
The metal feels colder because it is
insulating heat from leaving your hand.
Question 9
9.
Pick the correct statement about the cake coming out of the oven.
The cake is cooler because it doesn't instantly burn your hand.
The pan is hotter because it does instantly burn your hand.
The cake and pan are generally the same temperature.
Question 10
10.
What can be said about the cake below that is correct. Read all of them slowly before you answer.
The cake feels cooler and doesn't burn you because it is a poor conductor.
The pan feel hotter and burns you because it is a good conductor.
The cake feels cooler and doesn't burn you because it is a good inulator.
The pan feel hotter and burns you because it is a poor insulator.
None of the above 4 statements are correct.
All of the above 4 statmens are correct.
