Question

A certain freezing process requires that room temperature be lowered from 30°C at the rate of 5°C every hour.What will be the room temperature 5hours after the process begins?

Answer 1

Room temperature before the freezing process starts = 30°C

Rate of cooling = 5°C per hour

Temperature lowered in 5 hours = 5 x 5 = 25°C

Final temperature = 30 - 25 = 5°C

Therefore the Room temperature after 5 Hours is 5°C

Hope it helps!!
