Why the bimetallic strip bent with the heat?
A bimetallic strip is made up of two metals (the prefix "bi-" means "two"). The two metals have different coefficients of thermal expansion.
Bimetallic strips composed of two different metals each having a different rate of thermal expansion are used in?
Thermostats,.
A bimetallic strip used in thermostats relies on the fact that different metals have different?
Rates of physical expansion, over the same temperature change.
Does specific heat capacities have anything to do with different metals in a bimetallic strip used in a thermostat?
The principal thing is linear expansion rates as temperatures rise, different metals have different rates of expansion. In a bimetallic strip, one layer of one metal is fused onto one layer of another metal with a different linear expansion rate, when heated the strip will curve along its length due to the different expansion rates, the greater the temperature rise, the more the curvature, this movement is used to trip a switch.
Why are bimetallic strips used in thermostats?
The two metals chosen for the bimetallic strip have different modulii of thermal expansion, The bimetallic strip bends as the temperature changes and so the strip can be used to activate relays or other electronic switches and so work as a thermostat.

Why is a bimetallic strip curve when it is heated or cooled?
Because the two metals have different coefficient of linear expansion

What is the principle of the bimetallic or the compound bar?
A bimetallic bar has two different metals bound together. Different metals have different coefficients of thermal expansion. As the temperature changes, the metals will expand or contract different amounts - consequently the bar will curve on the side of the one that expands the least or contracts the most (depending on whether it is warming up or cooling down).

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.
What happens to bimetallic strip when it is heated and cooled?
The two metals have different expansion rates when the strip is heated. This means that one of the metals will expand more than the other, causing the strip to bend.
What is a bimetallic strip used in?
Bimetal strips can be used for thermocouples. The two metals will have different expansion rates and the difference will generate a small amount of electricity. The electricity generated can be collated to a given temperature. Your mom
Which material can be used as bimetallic strip?
You may use any two metals which have different thermal expansion properties. Steel and brass are commonly used because of cheapness. There is not even a need for them to be metals - you could bond two glasses of different thermal properties, and these would bend as well.
What happens when the Bimetallic Strip cools down?
When the bimetallic strip cools down, the metals in the strip contract at different rates due to their varying coefficients of thermal expansion. This differential contraction causes the strip to bend, with the side of the metal with higher expansion coefficient (usually the inner layer) being on the inside of the curve.
