Answer #1

Ans 1 :

The heating and cooling curves of a substance show the physical changes of the substance.

These changes occur in response to increasing or decresing pressure and temperture conditions of the system.

One axis of the graph shows the varying temperature of pressure conditions and the other one shows the amount of heat added to the substance.

The curve in the graph shows the physical transition of the states and depict melting/freezing and vaporization / condensation conditions.

Nippon Steel’s expenses for heating and cooling a large manufacturing facility are expected to increase according to an arithmetic gradient beginning in year 2. If the cost is $550,000 this year (year 0) and will be $550,000 again in year 1, but then it is estimated to increase by $49,000 each year through year 12, what is the equivalent annual worth in years 1 to 12 of these energy costs at an interest rate of 12% per year?
