Heat and Energy

Two students were studying properties of water.  One student placed a cup of 100ml of water into a beaker on a burner to boil.  Another student placed an identical cup containing 200ml  of water in an identical beaker on another burner to boil.  Which of the following will be the same for both cups of water?

• the temperature at which the water boils
• the mass of the boiling water
• the time it takes the water to boil
• the volume of the boiling water

Which process does the diagram show?

• freezing
• boiling
• evaporation
• melting

Nash puts his cold Coke Slurpee on to the metal roof of his mom's car. Describe the heat transfer that takes place.

• Heat is transferred from the car's roof into the Slurpee and increases the temperature of the Slurpee.

• Heat is transferred from the Slurpee into the roof and increases the temperature of the roof.

• The Slurpee stays the same temperature until it is completely gone.

• The roof doesn't change temperature due to the fact that it sits in the sun all day.
