Calculate a rate of cooling down of air from 80 c to 5c show calculation. give an answer in cubic meters per minute and cfm.

Explanation:

Given that,

Rate of cooling of air

Initial temperature= 80°C

Final temperature = 5°C

We need to calculate

Using newton's law of cooling

Where,

Here,

= 25°C  (surrounding temperature)

dt = 1 minute

Put the value into the formula

Hence, This is the required answer.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
