Question

2. Sheldon was doing a science experiment about temperature. He first measured the

temperature of some water and found it was 17°C. Then he put the water in the freezer and
recorded the temperature two hours later. It had fallen to -11°C. What was the change in
temperature in two hours?

Answer 1

Temperature dropped by 28°C in two hours

Explanation:

Initial measurement:

• t = 17°C

Measurement 2 hours later:

• t = - 11°C

The difference:

• -11°C - 17°C = -28°C

Temperature dropped by 28°C in two hours
