• Question 29
60 seconds
Q. Jake says his thermometer reads 65 degrees and Jessie says her thermometer says 18 degrees.  Their teacher says they are both correct.  How is this true?
Jake is in a different country than Jessie.
The teacher likes Jake better.

• Question 30
60 seconds
Q. If you place a cold cup of water in the direct sunlight on a hot day, what change will take place in the thermal energy of the particles that make up the water?
The particles will remain the same.
The solar energy will cause the particles will slow down because the sun will make the water warmer.
The particles will become smaller when the sun's energy heats the water up.
The solar energy will cause the water to warm up.  This will cause the particles of water to change from moving very slowly-less thermal energy (when cold) to moving quickly as they gain thermal energy (warm up).
• Question 31

Q. Why do you want to live in a home with good insulation during the cold winter months?
The insulation will keep you cool during winter.
If there is good insulation, the thermal energy will not be able to move easily from inside the warm home to the cool areas outside the building.
If there is not good insulation, the air inside the home will become too hot.
A house with good insulation will keep the warm air in the attic.
