At 8: 00, the temperature was 6 degrees Celsius (°C). Three hours later, the

temperature was -13°C.
By how many degrees Celsius did the temperature change?

Is the answer 19°C

Yes, 19 degrees.

thanks

You're welcome.

To find the change in temperature, we need to calculate the difference between the two temperatures: 6°C and -13°C.

To do this, we subtract the initial temperature from the final temperature. In this case, -13°C minus 6°C. The negative sign in front of the -13 indicates a temperature below zero.

-13°C - 6°C = -19°C

Therefore, the change in temperature is -19°C. The negative sign indicates that the temperature decreased by 19 degrees Celsius.
