A thermostat is a common application of a thermal expansion. It works as an indicator with an internal liquid that rises up if the temperature in the room also heats up.
This increase of volume is called expansion
Thermal expansion has been used to create many different devices including the fire sprinkler. Fire sprinklers have a bimetallic strip which will bend to one side when heated to connect to electricity and trigger the sprinkler.Ê
volume increases ,pressure increases
Depends on your application. The Thermal Expansion Coefficient is a number which represents how much a material will physically expand with an increase in temperature. If you want it to grow as it heats, it is the better material.
it was a hot night and a thermal one too
one example of thermal expansion is when in the kitchen and you can not open a can of vegetable(example) you will put it in a pan of hot water and the water will push it off.
Cement laying, for one job.
To lift hot air balloons
The one with the higher coefficient of thermal expansion.
Thermal expansion coefficient is how matter reacts to temperature, one of the best places to find information for free is at your local library in the encyclopedia or online in a few places, Wikipedia is often a good source for research, there are also various engineering sites that will show up from searching the words "thermal expansion coefficient" that will give the information,
The function of an expansion valve is to regulate the flow of a substance. One example is a thermal expansion valve which regulates the flow of cooling substances within a device.
Put ice in the inside one and rub the out one. The ice will result in thermal contraction and the friction in thermal expansion. Neither will be large but should be sufficient.
