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 the shade. Which of the following is the most likely temperature of the water in the shade?

• 0°C

• 25°C

• 30°C

• 35°C

Answer explanation

Both objects in heat will be hot but the one in direct sunlight will always be warmer than the one in shade.
