Unit 6.1 Water Cycle

You boil water in a pot, what happens to the motion of the water particles and why do you think this occurs?

• The speed of the particles will decrease because there is increased friction between the water particles.

• The speed of the particles will increase because the thermal energy of the water in the pot increases.

• The speed of the particles will decrease because the particles are moving farther apart.

• The speed of the particles will increase because the water particles are breaking apart.

You keep a pot of water boiling for 15 minutes. You observe that there is less water in the pot. The pot is not leaking. What happened to the water in the pot?

• The water particles were broken into smaller pieces.

• The water particles got smaller and now take up less space.

• The water particles became a gas and are now part of the air.

• The water particles disappeared and no longer exist.

In a pot of boiling water, you add 5 ice cubes. The ice cubes melt quickly. What is happening to the thermal energy of the ice cubes as they melt?

• The thermal energy of the ice cubes is increasing.

• The thermal energy of the ice cubes is decreasing.

• The thermal energy of the ice cubes is staying the same.

• There is not enough information to tell what is happening to the thermal energy of the ice cubes.

Water droplets have formed on the outside of a bottle. The water droplets started to flow down the bottle. What causes the water to move this way?

• The air pressure near the bottle is increasing.

• There is less friction on the surface of the bottle.

• The force of gravity is acting on the water drops.

• The thermal energy of the bottle is decreasing.
