Question

A certain freezing prosess requires that the 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 1

Initial temperature = 400C Rate of change in temperature = 50C/hour Time = 10 hours So, in 10 hours the temperature would be decreased by 10 × ...

Answer 2

Room temperature - 40 C

Room temperature - 40 Ct is also given that the room temperature lowers at the rate of 5° C, After one hour the temperature becomes (40 – 5) = 35° C

Room temperature - 40 Ct is also given that the room temperature lowers at the rate of 5° C, After one hour the temperature becomes (40 – 5) = 35° CAfter two hours the temperature becomes (35 – 5) = 30° C

Room temperature - 40 Ct is also given that the room temperature lowers at the rate of 5° C, After one hour the temperature becomes (40 – 5) = 35° CAfter two hours the temperature becomes (35 – 5) = 30° CHence after 10 hours the temperature becomes (-10° C)
