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.

Can anyone explain the use of a bimetallic strip in heat regulation in an electric iron?
When the temperature of the iron increases, the bimetallic strip bends upwards. This breaks the contact between the strip and the heating coil. When the temperature falls, the bimetallic strip bends down and the contact is restored.
How could a bimetallic strip be used to help in every day life?
A bimetallic strip can be used in thermostats to control temperature by bending due to temperature changes. This can be seen in appliances like ovens, refrigerators, and irons where the bimetallic strip acts to regulate the temperature setting.
How bimetallic strip works?
Scroll down to related links and look at "Bi-metallic strip - Wikipedia".
What is the use of a bimetallic strip in a thermostat?
A bimetallic strip in a thermostat is used to bend or curve in response to changes in temperature. As it heats up or cools down, the bimetallic strip moves, which in turn triggers the thermostat to turn a heating or cooling system on or off to regulate the temperature in a space.
How does a bimetallic strip act as a switch?
A bimetallic strip consists of two different metals with different coefficients of thermal expansion bonded together. When heated, the metals expand at different rates, causing the strip to bend. This bending can be used to physically open or close an electrical circuit, acting as a switch.

What are the examples of Contraction in solid liquid and gas?
Solid: contraction occurs when a solid cools down and its particles move closer together, causing the object to shrink in size. Liquid: contraction takes place when a liquid cools and its particles lose kinetic energy, leading to a decrease in volume. Gas: contraction occurs when a gas is cooled and its particles move closer together, resulting in a decrease in volume.
Are volcanoes constructive?
Yes. What happens is when the lava cools down, it turns into rock.
What happens dogs in summer?
You have to put them in front of a low fan that cools them down in the summer!
What happens to water vapor when it cools down?
When water vapor cools down, it undergoes condensation and turns back into liquid water. This process releases heat energy into the surrounding environment.
