b)−2° C

Step-by-step explanation:

hello! To solve this problem you should remember how are the operations with negative numbers, for this the only thing we must do is make a subtraction between the initial temperature (8° C) and the negative change of temperature (10° C)

Ti= initial temperature =8° C

ΔT= temperature change  =10° C

new temperature=Ti-ΔT

new temperature=8° C-10° C=-2° C

in conclusion the answer is -2° C
