What type of thermometer uses expansion and contraction of solid?

Bi-metal control thermometers. They are made from two strips of different metals joined together. When the strip is heated, one metal expands more than the other type, causing the strip to bend towards the side with the least expansion. At some point in the movement the metal will interact with a sensor which, in turn may control a switch which turns off or regulates the heat source. (btw this is called thermostats) It might be Bi-metal but that's what my science book says.

What type of weathering is caused by expansion and contraction of the rock?
Frost wedging
What type of physical weathering is caused by the expansion of?
Frost wedging
What type of solid is pure sodium classified as?
Pure sodium is a metallic crystalline solid.
Can a mercury thermometer be used to measure temperature between 500 and 600?
No, you need another type of device as a thermocouple.
Which is the suitable thermometer for measuring the boiling point of water?
A good thermometer for measuring the temperature of boiling water is one that is calibrated so that 100oC is in the mid to upper range of the scale. A typical alcohol thermometer usually works nicely.
How does a thermomerator measure temperature?
that depends on what type of thermometer. The tube thermometer, the kind with a glass tube with a red liquid in it, uses a small amount of mercury in a very small tube. When the mercury is heated, it expands, pushing further up the tube, as it cools it contracts, going down the tube. A dial thermometer also works on expansion and contraction, but with a coil instead of mercury.
What type of changes occurs in thermal expansion and contraction?
These are physical changes. No new substance is produced.
What type of weathering is caused by expansion and contraction of the rock?
Frost wedging
What type of policy does the fed to counteract a contraction?
The fed uses an expansionary monetary policy when dealing with a contraction. On the other hand, when dealing with a expansion that is resulting in higher interest rates, the fed uses a tight money policy.
What is the function of a master cylinder compensating port?
Type your answer here... Correct Answer: Allow for the normal expansion and contraction of brake fluid due to temperature changes
What type of policy does the fed use to counteract a contraction?

What does a thermometer that uses a solid look like?
It will probably be a "dial" type. In one case, it will have a metalic coil that expands and contracts with temp changes.
Why is a thermostat a special kind of thermometer?
A thermostat is not a thermometer, it is a device that routes 24 volts to various circuits according to temperature. There were old fashioned type mercury bulb thermostats but they are very rare today, most thermostats are solid state circuit board type.
Which type of muscular contraction is defined as a contraction which moves against a constant resistance?
isometric contraction
Physical property of bimetallic thermometer?
Basically you have two different kinds of metal with different coefficents of expansion put together. As they expand it creates a curving effect because one is expanding more than the other. This drives the needle and gives the indication. http://en.wikipedia.org/wiki/Bi-metallic_strip
What type of muscle contraction is involved in warming up?
isotonic contraction!
What type of matter is rubber?
Rubber is a flexible solid - (assuming you are referring to rubber bands, tyres, etc.) - Chemically why it is both requires expansion.
