This law states that the mass of products obtained from a chemical reaction equals the mass of the substances that react. Every known chemical reaction that has been studied follows this law. 30 to proceed. Upon completion of the reaction, we would find that the mass of the blue-green liquid plus the mass of the red gas is equal to the masses of our starting materials. When nuclear reactions were discovered—such as the fusion reactions that power our Sun—scientists realized that processes that release very large amounts of energy do not conserve mass.

To classify the items, they observed similarities and differences in properties. They were making observations to help them understand nature. Observation is one of the tools of scientific inquiry, but it is not the only one. The scientific method is an approach to asking questions and seeking answers that employs a variety of tools, techniques, and strategies. Although the scientific method is often explained as a series of steps and procedures, it is more accurately described as a way of looking at the world that differs from nonscience forms of inquiry.

In the United States, we often use the Fahrenheit scale to measure body temperature and air temperature. Fahrenheit is rarely used in science. Two other temperature scales are standard: the Celsius scale and the kelvin scale. 22. Another property of matter that is independent of sample size is the temperature at which the substance changes from one physical state to another. The boiling point is the temperature at which the liquid form of a substance changes to the gaseous form. At the melting point, the substance changes from a solid to a liquid.
