Physical properties are characteristics of matter that can be observed without making any changes to the chemical composition of that given matter. In academic contexts, physical properties are often contrasted with chemical properties.
When chemists discuss physical properties, they are talking about characteristics that can be observed without interfering with molecular structure or taking other steps to change matter. These characteristics include things like color, which can be easily observed in elements like gold; texture, which is easy to determine with something like water; and boiling point, which doesn't require any changes to a given material other than the application of heat.Learn More
Xenon is the heaviest of the noble gases with a density of 5.84 grams per liter. It is colorless, odorless and tasteless. This nontoxic gas, while considered inert, forms compounds with oxygen and fluorine that are all toxic due to their strong oxidation potential. Exciting the gas in a vacuum tube using electricity causes a blue glow.Full Answer >
According to Elmhurst University, the five physical properties of matter are color, odor, shape, mass and texture. Other physical properties of matter relate to its freezing and boiling points, density and solubility.Full Answer >
Water has numerous physical properties, including the color, surface tension and adhesion. There are far more physical properties than chemical properties. This is partially due to water taking so many forms, such as ice or steam; each form of water has different properties.Full Answer >
Percent composition is important because it helps one to know the chemical composition of certain substances. Percent composition is used to calculate the percentage of an element in a mixture. One can also derive an empirical formula from percent composition. The empirical formula derived from percent composition can help one find the actual molecular weight.Full Answer >
