Two different metals are used to make a bimetallic strip because each metal expands and contracts at different rates when heated or cooled. This difference in thermal expansion causes the strip to bend, making it useful in applications such as thermostats and thermal switches.

What is the thermometric substance of bimetallic thermometer?
Ah, the thermometric substance of a bimetallic thermometer is actually the two different metals that make up the strip inside. These metals expand at different rates when heated, causing the strip to bend. It's like a little dance they do together, showing us the temperature changes in a beautiful and simple way. Just imagine those metals dancing in harmony, creating a lovely symphony of temperature readings for us to enjoy.
A bimetallic strip will bend when heated because?
a bimetallic strip consists of two different metals with different thermal expansion coefficients. When heated, these metals expand at different rates, causing the strip to bend due to the resulting difference in length between the two metals.
Why are two different metals needed when making a bimetallic strip for a thermoteter?
Two different metals are needed in a bimetallic strip to take advantage of their different thermal expansion properties. When heated, one metal expands more than the other, causing the strip to bend. This bending action is used in thermometers to measure temperature changes.
How could a bimetallic strip be used to make a thermometer?
A bimetallic strip can be used in a thermometer by attaching one end to a pointer and placing the other end in contact with a temperature-sensitive substance. As the temperature changes, the bimetallic strip will bend due to the different rates of expansion of the two metals, causing the pointer to move and indicate the temperature on a scale.
How is a bimetallic strip used in a thermostat?
A bimetallic strip is used in a thermostat, by concealing it inside. When the temperature goes up, the bimetallic strip expands, and turns on the circuit for the AC/compressor ,to make the temperature cooler inside wherever the thermostat is.Two metal strips of differing thermal expansion are bonded together. Because the expansion is different the metals expand by different amounts. When heated the strip therefore has to bend, the one with the greater expansion on the outside of the curvature. As the strip bends it can either make or break a circuit contact depending on the configuration of the circuit, switching on of off the current. The reverse is true when the strip cools again.
How do you make a circuit using bimetallic strip?
The bimetallic strip is made of two different metals, bonded together. The two metals have different temperature expansion coefficients, so when the bonded assembly is heated or cooled, it curves one way or the other, allowing a switch to be opened or closed.

How could a bimetallic strip be used to help in every day life?
A bimetallic strip can be used as a thermometer or thermostat. The two metals expand at different rates which will make it bend. You can use this to find the temperature of an oven. When the temperature of the oven increases, the strip will curve and break the electrical contact which make the oven cool down. When the oven cools the bimetallic strip will become straight again and the electrical contact will be remade and the oven will begin to reheat again.

Why does a bio-metallic strip curve when it is heated?
The two different metals welded together to make the strip have unequal rates of expansion when heated. The metal that expands furthest will force the lesser expanding metal to curve over and either make or break an electrical connection.
How does a bimetallic strip thermometer work?
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.
What is a bimetallic coin?
A bimetallic strip is often used in thermostats because it is quite simple to make and responds predictably to changes in temperature. The bimetallic strip is pretty much what it sounds like - a strip made from two metals. Inthermostatsit is common to make one side out of steel and the other out of copper - then bond them together. they are formed into a curving spiral. Different metals have different coefficients of thermal expansion so as the temperature changes, the spiral strip either curls up or uncurls as one side expands or contracts more than the other. The control isattachedto one end of the strip so that as it curls or uncurls, it rotates the control.Sometimes the control is a simple mercury switch that closes a contact whenrotatedone way and opens the contact when rotated the other. Sometimes one end is attached to a power source and the other end is connected to an electric contact, which moves as the strip curls and uncurls.You can also attach it to a pointer and have it point to temperatures on a dial.
Why do you use a bimetallic strip in fire alarms?
Bimetalic strips are composed of two metals with different properties in the case of fire alarms it is the difference in thermal expansion that is important. When the strip is heated (due to a fire) the strip bend and can complete an electric circuit setting off the alarm.
How could a bimetallic strip perform a practical task in life?
bimetal stip is next to the contacts it make your oven,iron and air conditions unit work that is when ever the contacts touch from how high you put it and it heat up and the iron and brass bends
