Question

A certain freezing process requires that room temperature be lowered from 40°C at the rate of 5°C every hour. What will be the room temperature 10 hours after the process begins? ​

Answer 1

Answer:

-10°C

Step-by-step explanation:

1. If temperature lowers by 5°C per hour, after 10 hours the temperature will be lowered by 5°C x 10 hours = 50°C

2. Hence, the temperature after 10 hours = 40°C - 50°C = -10°C
