Heat Energy Review Quiz

Answering which question would help a student decide that sunlight is a source of heat energy?

• Why do car tires feel warm after driving?

• Why does water boil in a pot on a hot stove?

• Why do ice cubes melt in a glass of water outside?

• Why can rubbing two sticks together create a fire?

Read the passage about a student and his bicycle.

A student is performing an investigation. He uses a thermometer to measure the temperature of his bicycle tires. Next, he rides around his neighborhood for thirty minutes. After his ride, he measures the temperature of the tires again.

What question is the student most likely trying to answer?

• How far can a bicycle travel in thirty minutes?

• How much does the sun heat up the ground?

• How fast can the bicycle travel at top speed?

• How much heat energy is caused by friction?

Which of these benches is most likely the warmest?

• 
• 
• 
• 

Grace and Tyler were outside on a sunny day. Grace wore a

white shirt and Tyler wore a black shirt. Why did Tyler feel

hotter than Grace?

• He was sitting far away from Grace.

• Dark colors take in the Sun's energy.

• He was sitting closer to the ground than Grace.

• Dark colors push away the Sun's energy.

The pictures show Tonya and Caleb each pushing a box

across the carpet. Tonya's box has wheels and Caleb's box

does not.

After pushing the boxes across the floor, whose box would

most likely feel the warmest on the bottom and why?

• Tonya's box would be the warmest because the

  wheels would create more friction.

• Tonya's box would be the warmest because the

  wheels would create less friction.

• Caleb's box would be the warmest because there

  would be more friction created without the

  wheels.

• Caleb's box would be the warmest because there

  would be less friction created without the

  wheels.

Zara rubbed a wooden dowel with a cloth for 10 seconds.

Then she rubbed the dowel with sandpaper for 10 seconds.

Which made the dowel hotter, and why?

• the sandpaper because it is darker and absorbs

  more heat

• the cloth because it creates a chemical reaction

  and absorbs more heat

• the sandpaper because it is rougher and creates

  more friction, creating more heat

• the cloth because it is more flexible and creates

  more points of friction, creating more heat

Ross rode fast on his bicycle. When he felt the tires after he

stopped, they were warmer than before he started. Why were

the tires warmer?

• The tires burned on the road to create heat.

• The tires rubbed on the road to create heat.

• The tires melted into the road to create heat.

• The tires mixed with the road to create heat.

Which question would help a student find out if friction is a

source of heat energy?

• Why does snow disappear in the spring?

• How long does it take water to boil on the stove?

• Do objects feel warmer after rubbing them

  together?

• What causes the ice cubes to melt in a glass of

  ice water?

The picture below shows a cup of water and a thermometer

on a sunny summer day, then the same beaker later in the

day in shade.

Which of the following is the most likely temperature of the

water in the shade?

• 0°C

• 25°C

• 30°C

• 35°C

The pictures below show the temperatures recorded by two

lab groups from the same thermometer at 3:00 p.m. on the

same day.

Why did the groups get different results?

• One of the groups did not use the correct

  language to record its measurement.

• The groups did not use the same thermometer

  to make their measurements.

• One of the groups measured the temperature at

  a different time of day.

• The groups decided to use a different unit to

  record the temperature.
