Answer:
23° F
Step-by-step explanation:
To find the change use the absolute value function, that is
| - 16 - 7 | = | - 23 | = 23° F
or
| 7 - (- 16) | = | 7 + 16 | = | 23 | = 23° F
T1=-16°F
T2=7°F
[tex]\\ \sf\longmapsto \Delta T=T_1-T_2[/tex]
[tex]\\ \sf\longmapsto \Delta T=-16-7[/tex]
[tex]\\ \sf\longmapsto \Delta T=-23°F[/tex]
