Question

When she woke in the morning Josie notices the temperature outside was -4.8*c. When she got home from school the temperature rose 15.6*c. What was the change in the temperature

Answer 1

20.4°C

Explanation:

Initial temperature 't1'= -4.8°C

Final temperature 't2'= 15.6°C

In order to find change in temperature, take the difference of above two temperatures. So,

Change in temperature 'ΔT' = t2 - t1

ΔT= 15.6 - (-4.8)

ΔT= 20.4 °C

Therefore, the change in temperature was 20.4°C
