CLICK TWO:

What are two things found inside the soda can?

• Water

• Air molecules

• Salt

• Fire

What does heating up water do?

• It provides energy to water molecules.

• It slows down the water molecules.

• It makes the soda taste bad.

• It explodes the soda can.

CLICK TWO:

Describe the movement and arrangement of water molecules as temperature increaeses.

• They move faster.

• They move slower.

• They take up more space.

• They take up less space.

Once enough energy is added, water changes its state of matter from ​ (a)   to ​ (b)   . We call this "water vapor."

• liquid
• gas
• solid

How does water vapor increase the pressure inside the can?

• By pressing against the sides of the can

• By increasing the number of water vapors

• By turning into liquid water

• By leaving the soda can

What happens to water vapors (gas) as you quickly place the hot soda can into the cold water?

• Water vapor turns into liquid

• Water vapor explodes

• Water vapor becomes solid

• Water vapor takes up more space than before

Describe the amount of space water vapor takes up as it turns into liquid

• it takes up less space

• it takes up more space

• the amount of space it takes up does not change

What does the cold water do to the can?

• • It expands the air inside

• • It freezes the water inside

• It causes the water vapor to shrink

• • It makes the metal stronger

Why does the can implode when put in ice water?

• The pressure changes due to the temperature difference

• • The water gets into the can, causing the can to shrink

• • The can is too thin to withstand the cold temperature

In this lab, you learned that increasing temperature causes volume to ​ (a)   . Decreasing temperature causes volume to ​ (b)   .

• increase
• decrease
