Matter typically exists in one of three states: solid, liquid, or gas. … Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids. Most metals exist as solids at room temperature. All substances can exist
Can A Chemical Property Be Observed Just By Looking At A Substance? Chemical properties are very useful in identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance. Can you determine a chemical property of a substance by just
How Does Understanding The Physical Properties Of Substances Help To Classify And Compare Them? These physical properties can be used to classify substances. For example, in the case of physical state, a substance can be either a solid, a liquid, or a gas. Water is liquid at room temperature. … You can also classify substances
What Can Be Observed Without Changing The Composition Of Matter? Physical properties are used to observe and describe matter. Physical properties can be observed or measured without changing the composition of matter. These are properties such as mass, weight, volume, and density. When a substance undergoes change that does not change its composition the change
