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.Know More
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
Bimetallic strip thermometers are comprised of two fused pieces of different metals that expand at different rates when heated. A pointing device is attached to the pieces of metal, and when the metals are heated, one piece expands faster than the other, causing the metal combination to bend and allowing the pointing device to move up or down a scale of degrees. When the metals cool, they move back to their original shape, allowing the pointing device to also move back down the scale.Full Answer >
Fermi level is used to describe the top of the collection of electron levels at absolute zero temperature. This concept is derived from Fermi-Dirac statistics.Full Answer >
Thermal energy is used primarily for heating and cooling buildings and for certain industrial processes. Wood and pellet stoves are commonly used to heat homes. Certain factories can use thermal energy to create steam to run their production sites. This is known as biomass thermal energy.Full Answer >
Thermal energy is used to describe energy in a heated form. Thermal energy is transferred in three different ways: radiation, conduction and convection.Full Answer >
