Question

A certain freezing process requires that room temperature be lowered from 40degree at the rate of 5degree every hour what will be the room temperature after 10 hours the process begins pls help me

Answer 1

Answer:

Initial temperature = 40° C

Rate of change in temperature = 5°C/hour

Time = 10 hours

So , in 10 hours the temperature would be decreased by 10*5 = 50°C.

So , final temperature = 40–50

= –10°C.

I hope this will help you
