Sam is doing an experiment to see if the temperature of an object changes when rubbed against another object. To do this, Sam takes the temperature of her skateboard's wheels. The temperature reads 77°F.

Which of the following could be the temperature of her skateboard's wheels right after she rides her skateboard for several minutes on the rough concrete?

• 32°F

• 86°F

• 68°F

• 77°F

John pushed a box of books across a carpeted floor. Then he pushed the box of books across a tiled floor. Which most likely caused the bottom of the box to have a greater increase in temperature, and why?

• the carpet because it created more heat energy, which created more friction

• the carpet because it created more friction, which created more heat energy

• the tile because it created less friction, which created more heat energy

• the tile because it created less heat energy, which created more friction

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.

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

• 30°C

• 35°C

• 25°C
