Question

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

Answer 1

Answer = The room temperature will be - 10°C after 10 hours if the room temperature is lowered from 40°C at the rate of 5°C every hour

Explanation :-

We know that a certain freezing process requires that the room temperature be lowered from 40°C at the rate of 5°C every hour.

We need to find out the temperature 10 hours after the process begins.

Thus we get,

=> 5 × 10 = 50

Final temperature = 40 - 50

= -10°C
