Amplify Thermal Energy Vocabulary Test

In some places, hot water from underground can shoot up into the air through a hole in the ground. When this happens, the ground surrounding the water increases in temperature. What happens to the molecules in the ground when the temperature of the ground increases?

• More heat molecules combine with the molecules in the ground.

• The energy of the molecules in the ground decreases.

• The energy of the molecules in the ground increases.

• The cold energy of the molecules in the ground decreases.

Lin cooked a pot of soup, then put half the soup in the freezer for a while. Now the soup in the pot is hot, and the soup in the freezer is cold. What is the difference between the molecules of the soup in the pot and the molecules of the soup in the freezer?

• The molecules of the soup in the pot are moving and the molecules of the soup in the freezer are not moving.

• The molecules of the soup in the pot are moving faster than the molecules of the soup in the freezer.

• There is no difference because all of the soup is made of the same type of molecules.

• The molecules of the soup in the freezer are smaller than the molecules of the soup in the pot.

Rico and Bree are camping and have potatoes wrapped in foil to eat. Bree put her potato in the campfire for a while, but Rico did not. Now Bree’s potato has a high temperature. What is the difference between the molecules of the two potatoes?

• There is no difference because both potatoes are made of the same type of molecules.

• The molecules of Rico’s potato are smaller than the molecules of Bree’s potato.

• The molecules of Bree’s potato are moving and the molecules of Rico’s potato are not moving.

• The molecules of Bree’s potato are moving faster than the molecules of Rico’s potato.
