Question

A certain freezing process requires that room temperature be lowered
from 30°C at the rate of 5°C every hour. What will be the room
temperature 5 hours after the process begins?

Answer 1

Answer:

5°c

Step-by-step explanation:

5°*5hours=25°

so 30~25=5

Answer 2

In the first hour, the temperature will reduce from 30°C to 25°C.

In the second hour, the temperature will reduce from 25°C to 20°C.

In the third hour, the temperature will reduce from 20°C to 15°C.

In the fourth hour, the temperature will reduce from 15°C to 10°C.

In the fifth hour, the temperature will reduce from 10°C to 5°C.

Thus, the room temperature will be 5°C after 5 hours.
