Question

A certain freezing process requires room temperature to be lowered from 60°C at the rate of 8°C every
hour. What will be the room temperature, 8 hours after the process begins?​

Answer 1

The present room temperature = 40\degree C40°C

The room temperature decreasing every hour by rate of = 5\degree C5°C

The room temperature after 10 hours will be

= 40\degree C\ +\ 10\times\left(-5\degree C\right)40°C + 10×(−5°C)

= 40\degree C-50\degree C\40°C−50°C

= -10\degree C−10°C

so, the room temperature after 10 hour = -10\degree C−10°C
