a) Copper is at a higher temperature, so the flow of heat will take place from copper to iron. Heat is a form of energy, which always flows from higher temperature to lower temperature.
b) To determine the actual final temperature, the heat capacity of the calorimeter must be known. A calorimeter constant refers to a constant, which quantifies the heat capacity of a calorimeter. It may be determined by using a known amount of heat to the calorimeter and measuring the corresponding change in temperature of the calorimeter.
The original options for this question were cleavage, luster and hardness. The answer would be cleavage.
Answer: 1.8 x 10^1 or the scientific e notation is: 1.8e1
Fe2O is the formula for that
The amount of absorption force is not same at all time and at all where .
It has difference at different time periods
So during those the curve goes up and down and repeat this flow
So there are dips
