How does a bimetallic strip thermometer work?

Answer 1

It has two types of metal so when you put it on top of a candle it always curls the same way even if you flip it over........... I don't know what it's used for i have only seen it used once in a grade seven science class so that is all i know bout it.

Answer 2

A bimetallic strip is used in physics to show expansion of metals. Different metals expand in different amounts when exposed to heat. When you heat a bimetallic strip, one metal will expand more than the other so the strip will bend to one side.

Answer 3

A bimetalic strip is two different kinds of metals fused together. When you heat it up, the dissimilar stretch rates causes it to bend. It can drive a contact that turns a heating element on and off, thus operating as a thermostat.

Answer 4

Different metals have different coefficients of expansion. They expand and contract at different rates, depending on what they are made of.

If you take two dissimilar metal strips and glue, or weld, them together, as one changes size compared to the other, it will cause the combined strip to bend.

This is useful for temperature measurement.

You can either attach a pointer through gears and levers, to amplify the movement, or make it operate a switch for electrical control.

Answer 5

It is an experiment that demonstrates thermal expansion. Two metals with different thermal expansion coefficients are bonded together and when heated, one will expand more than the other, causing the strip to bend to one side. No matter which way you direct the flame, the metal which expands more will bend in the same direction. This is used as a thermometer because the more intense the heat, the bigger the curve.
