plz mark me as brainliest :)
Answer:
6.575
Explanation:
T1 = 30C = 30 + 273 = 303 K
T2 = - 10 C = - 10 + 273 = 263 K
The coefficient of performance of heat pump
k = T2 / (T1 - T2)
k = 263 / (303 - 263) = 6.575
The answer is A because it gives you a straight line which would make it easy for you go just go to end fast as a car .
