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
thermal expansion can be used in bimetalic strips in tehrmostats
it can also be used in lossening nuts and bolts
A thermometer works by using the thermal expansion of a liquid to measure temperature.
A hot-air balloon uses the thermal expansion of air to generate lift.
baloon,steem engine,and the most thermometer
a thermostat.
This increase of volume is called expansion
it was a hot night and a thermal one too

The one with the higher coefficient of thermal expansion.
Thermal expansion in solids is normally very small - typically around one part in one hundred thousand for a one Kelvin temperature change. That means that a one metre long length of aluminium, for example, will only change size by 0.23mm when heated by 10kelvin - effectively invisible to the human eye. Thermal expansion, though can be visible to the unaided eye if the object is large enough - a kilometer long bridge, for example, may vary in length by as much as a metre or more between summer and winter, depending upon the seasonal temperature change, and will have expansion joints that allow sections of the bridge to expand into one another without changing the overall length of the bridge, and risking damage to the structure. If you were to look at these joints in winter and then in summer, you would see the difference that thermal expansion makes.
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
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.

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.
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.
