An example of a bad insulator is glass. An insulator is a material that does not allow much heat or electricity to pass through easily.Know More
Examples of good insulators are polymers and ceramics. But, unlike ceramics, polymers melt at a low temperature. So, they are not suitable materials for anything that would experience a high temperature. In the case of glass, it is not an appropriate material for external doors such as patio doors of homes in very cold temperature zones because of its tendency to lose so much heat.
Glass is widely used in tableware such as bowls and packaging such as food storage jars and bottles for drinks. It is also used in electronics, automobiles, fiber optic cables and others.Learn more about Thermodynamics
According to HowStuffWorks, aluminum foil is a good insulator because it prevents the radiation of heat by reflecting it back at the source. Since aluminum foil reflects the emission of heat, it tends to be a better insulator than other materials that just slow down the flow of heat from one area to another.Full Answer >
Frost is formed on the inside of a window, when the air on the outside of the glass is cold enough to cause the interior water vapor to condense and freeze against the sufficiently cold inside surface of the glass. This is no longer a common occurrence, because most homes now have double-pane windows that are much better thermal insulators. Older glass windows, however, could produce elaborate interior frost patterns because the ice crystals would form around scratches, streaks or other imperfections on the interior glass surface.Full Answer >
One example of a science project involving insulation is to measure the effects of an insulating container on the transmission of heat from a warm beverage. The comparison involves measuring temperatures at which people could comfortably pick up a cup of that beverage, using cups made of different materials.Full Answer >
A classic example of an endergonic reaction is a synthesis reaction, where simple molecules combine to form complex compounds. An endergonic reaction requires the input of free energy to initiate the process.Full Answer >
