Full Answer

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.

    What are the physical properties of xenon?

    A:

    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.

    What are the physical properties of water?

    A:

    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.

    What is the chemical composition of orange juice?

    A:

    There is not a chemical composition for orange juice. Orange juice is called a mixture, which is a combination of at least two different substances. Because each of these substances retain their own chemical identity when they are mixed together, no universal chemical formula for orange juice is possible.
