Question

Temperatures 26${}^{\circ }$C above 0${}^{\circ }$C and 13${}^{\circ }$C below 0${}^{\circ }$C can be represented as:

• A. -26^oC and +13^oC
• B. +26^oC and -13^oC
• C. -26^oC and -13^oC
• D. +26^oC and +13^oC

Answer 1

The correct option is B

+26^oC and -13^oC

We can take 0${}^{\circ }$C as the midpoint and anything above/greater than 0${}^{\circ }$C as positive and less than 0${}^{\circ }$C as negative.

Thus, 26${}^{\circ }$C above 0${}^{\circ }$C = + 26${}^{\circ }$ and 13${}^{\circ }$C below 0${}^{\circ }$C = -13${}^{\circ }$C .
