Oxidized silver is silver that has been exposed to oxygen in a pressurized environment for a long period of time. It is different from traditional silver because it is a darker color and has very little luster.Continue Reading
Pure silver must generally be polished and cleaned on a regular basis to keep it from becoming tarnished. It should not be placed in areas where it will be exposed to large amounts of oxygen and should be taken care of in special silver storage containers. Oxidized silver will not be affected by the tarnish and the tarnish will allow the silver to take on a more oxidized work. Oxidized silver does not have to be polished or cleaned and can generally be left in any type of environment.
Pure silver is found only in the ground and is not combined with other elements to make pieces of jewelry or home decor items. It is the most reactive silver and will tarnish more quickly. Sterling silver is the most popular and common type of silver found in jewelry and home decor. It is combined with other metals to help prevent it from tarnishing. Sterling silver is much harder than pure silver and is able to stand up to daily use.Learn more about States of Matter
Silver freezes from a liquid into a solid at a temperature of approximately 1,762 degrees Fahrenheit. Conversely, silver also melts from a solid into a liquid when heated past that temperature. Because of this high melting point, silver is a solid at room temperature.Full Answer >
The process of a gas changing to a liquid is called condensation, and for condensation to take place, the environment has to reach maximum vapor pressure, generally through a lowering of temperature in the case of the water cycle. Because pressure varies inversely with temperature, as temperature decreases, pressure goes up, causing the gas molecules to move with progressively less kinetic energy. Eventually, liquid vapor and droplets form, and the gas begins to condense.Full Answer >
Ice can get as cold as its environment. For example, in a freezer with an ambient temperature of minus 40 degrees F, ice will continue cooling beyond the freezing point until it, too is minus 40 degrees F.Full Answer >
When a vapor or liquid in a closed environment reaches an equilibrium between the amount of evaporating, condensing and returning molecules, the liquid or vapor is saturated. Saturated vapor is also known as dry vapor.Full Answer >
