Question

aditya is in the process of making ice cream he has heated all the ingredients to 60 degree Celsius and put them in refrigerator to freeze if the cooling rate is 12 degree Celsius per hour what Will be the temperature in freezer after 11 hours answer in steps

Answer 1

Temperature before freezing = 60
Cooling rate = 1hr = 12 degree
11 hours = 12 × 11 = 132 degree
Temperature after 11 hours = 60 - 132 = - 72 degree



Hope it helps

Answer 2

Answer:

Final temperature of the ice-cream after 11 hours = -72° C

Step-by-step explanation:

Temperature of ice-cream before freezing = 60° C

Rate of cooling = 12° C per hour

Time the ice-cream is kept for freezing  = 11 hours

So, Temperature of ice-cream = 11 × 12

                                                  = 132° C

But the initial temperature of the ice-cream = 60° C

So, Final temperature of the ice-cream after 11 hours = 60 - 132

                                                                                            = -72° C
