Question

A cooling machine requires that room temperature to be lowered from 30°c at the rate of 5°c
every hour. What will be the room temperature after 8 hours of starting the process?
6 positive​

Answer 1

Answer:

The room temperature after 8 hours process begins is 10°C. So, Room temperature after 8 hours , it becomes, Hence, the room temperature after 8 hours process begins is 10°C.

Step-by-step explanation:

Hope it worked

Answer 2

Answer:

Room temperature at the beginning of the process = 50C

Rate of lowering the temperature = 5C every hour

Temperature lowered after 8 hours= 5 × 8 = 40oC

Room temperature after 8 hours = 50C - 40C = 10C
