Question

3) A certain freezing process requires that room
temperature be lowered from 400 C at the
rate of 50 C every hour. What will be the
temperature 10 hours after the process begins?​

Answer 1

Answer:

Step-by-step explanation:

Temperature of room = 400 C

Rate of decrease  = 50 C

so after 10 hours decrease = 10 * 50 C

                                             = 500 C

So, temperature is = 400 C - 500 C

                               = -100 C

Thus temperature after 10 hours is -100 C

Hope this helped u :)
