By how much will the temperature have risen if it registers\[\text{4 }\!\!{}^\circ\!\!\text{ C}\]?
A) \[\text{12 }\!\!{}^\circ\!\!\text{ C}\]
B) \[\text{0 }\!\!{}^\circ\!\!\text{ }\]
C) \[\text{16 }\!\!{}^\circ\!\!\text{ C}\]
D) \[\text{14 }\!\!{}^\circ\!\!\text{ C}\]
Correct Answer: C
Solution :
\[\text{4}{}^\circ \text{C-}\left( \text{-12}{}^\circ \text{C} \right)\text{=4}{}^\circ \text{C+12}{}^\circ \text{C =16 }\!\!{}^\circ\!\!\text{ C}\]
