Question

6. A certain freezing process requires that
room temperature be lowered from 80° C
at the rate of 10° C every hour. What will
be the room temperature after 10 hours the
process begins?​

Answer 1

Answer:

hence for 1 hour it decreases to 10c and after ten hours=10×10. =100 hences your total temperature after 10hours is. -20 degrees Celsius

Answer 2

Answer:

-20°c

Step-by-step explanation:

current temperature of a room =80°c

rate decreasing every hour =10°c

for 10hours rate of decrease = 80° - (10°*10°)

                                                = 80° - 100°

                                                = -20°
