Question

a certain freezing process requires that room temperature be lowered from 40degree Celsius at the rate of 5degree Celsius every hour what will be the room temperature 10hours after the process begins ​

Answer 1

Answer:

-10 degree

Step-by-step explanation:

Initial Temperature = 40°C

Rate of cooling = 5°C / hour

Time = 10 hours

Temperature reduced = Rate of cooling * Time

                                  = 5 * 10

                                  = 50° C

∴Final Temperature = 40 - 50 = - 10° C
