Step-by-step explanation:

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:-

Given:-

  • Room temperature is lowered than 40°C.
  • Rated temperature is 5°C/h.

To find:-

  • The temperature of the room after 10 h.

Solution:-

The present room temperature = 40°C

The room temperature decreasing every hour by rate of = 5°C

So,

The room temperature after 10 hours will be,

= 40°C + 10 × (-5°C)

= 40°C - 50°C

= -10°C

Hence, the room temperature after 10 hour = -10°C
