Question

A certain freezing process requires that the room temperature be lowered from 50°C at the rate
of 5°C every hour. What will be the room temperature 8 hours after the process begins?​

Answer 1

Answer:

Given that

Let us assume that the lowered temperature as negative,

Initial temperature = 50oC

Change in temperature per hour = -5oC

Change in temperature after 8 hours = (-5) × 8= -40C

∴The final room temperature after 8 hours of freezing process = 50oC + (-40oC)

= 10C

The room temperature 8 hours after the process begins= 10° C
