Chapter 1, Problem 23PS
A hot metal block is plunged into water in a well-insulated container. The temperature of the metal block goes down, and the temperature of the water goes up until their temperatures are the same. A total of 1500 J of energy' is lost by the metal object. By how much did the energy of the water increase? What law of science is illustrated by this problem?

Expressing amounts of energy in different energy units is necessary to solve many chemistry problems.
For practice, complete the following table.
The Joule (J) is the SI unit of energy.
The calorie (cal) is the amount of energy needed to raise the temperature of 1 g of water by 1°C.
1 cal = 4.184 J
The British Thermal Unit (BTU) is the amount of energy needed to raise the temperature of 1 pound of
water by 1°F. 1 BTU = 1055 J

We are doing an experiment on measuring the temperature. We are to measure the temperature of hot water (measure it initially, then wait for 10 minutes then measure again). Additionally, we are to measure the temperature of another water before and after putting ice (measure initially then measure 3 times [every 5 minutes] for 15 minutes). My question are:
What law or principles of chemistry could be applied in this experiment?
Should we expect the temperature of the hot water to drop? why?
Should we expect the temperature of the water to rise or drop after putting the ice? why?

Explain your reasoning. c Which of the experiments that you listed above are the most convincing in determining whether the compounds are the same?

He proceeds to take 10.0 g of each compound and places them in separate beakers, each containing 100 mL of water. Both compounds completely dissolve.
