A temperature of 6 °C below zero rises by 10 degrees and then falls by 3 degrees. What is the final temperature?
- 1 °C
- 7 °C
- 13 °C
- 3 °C
Show answer and solution
Correct answer: A. 1 °C
Rising 10 from 6 below zero gives 4 above zero, and falling 3 leaves 1 °C.
By how many degrees Celsius do the boiling point and the freezing point of water differ?
- 32
- 212
- 100
- 180
Show answer and solution
Correct answer: C. 100
Water freezes at 0 and boils at 100 degrees Celsius, so the gap is 100 degrees.
