Question

A certain freezing process require that room temperature be followed from 40c at the rate of 5c every hour. what will be the room temperature 10hours after the process begins​

Answer 1

$\large\color{black}{Step-By-Step \: Solution}$

The present room temperature = 40°C

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

The room temperature after 10 hours will be

$= 40\degree C\ +\ 10\times\left(-5\degree C\right) \\ = 40\degree C-50\degree C\ \\ = -10\degree C$

So, the room temperature after 10 hour = - 10°C.
