Answer:
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
