A bimetallic strip is used in thermometers. It can also be used in different applications, such as coils found in thermostats and electrical breaker boxes.Continue Reading
A bimetallic strip is comprised of two different metals. For it to be a bimetallic strip, the two metals must have different expansion coefficients. Brass and steel are common metals that are bonded together in a bimetallic strip.
When a bimetallic strip with brass and steel is heated, the brass will expand more the steel, causing the strip to curve with the brass on the outside. When the steel is cooled, it will curve with the steel on the outside. This works well in thermometers to help demonstrate the mercury rising as temperatures go up.Learn more about Thermodynamics
A cold fusion reactor is a vessel in which nuclear fusion takes place at or near room temperature. Normally, fusion requires incredible amounts of heat, enough to make it far too dangerous to attempt on Earth. As of 2014, no known method of achieving cold fusion exists.Full Answer >
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 >
An isobaric process is a thermodynamic process that occurs at constant pressure. In such processes, the volume of the substance or gas heated is allowed to vary with temperature. One example of an isobaric process is the expansion of gas to drive a freely moving piston.Full Answer >
Geothermal power is generated by capturing and utilizing the steam and hot water produced by geothermal springs. As cold water seeps into the Earth’s crust, a layer of hot and molten rock heats it up and causes it to rise to the surface, where it’s used to power turbines.Full Answer >
