Question

a certain freezing process requires that rooms temperature to be lowed from 60 c at the rate of 8c every hour. what will be the room temperature 8 hours after the process begins​

Answer 1

Answer:

-4c

Step-by-step explanation:

Initial temperature= 60c

rate of change of temperature= (-8)c/hr

therefore temperature 8 hours the freezing process has started= 60+(-8)(8)

= 60+(-64) = -4c

Answer 2

Answer:

1)The room temperature in after the 8 hours = 64c .

2)freezing beginning point is= 60 so 60-64 = 4c.

Given:

1)A certain freezing process required that room temperature to be lowed from 60 c at the rate of 8c every hour.

To find:

1) what will be the room temperature 8 hours after the process begin.

Step-by-step explanation:

1) Before in this room temperature was loyer than 60 c.

2)Increased the 8 c for every hour.

( Therefore 60+(-8)(8). )

so in this 8 was make multiplication.60+(-64).

since 60-64 =4 c

Hence room temperature in after the freezing

point = 4 c
