What else can I help you with?
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 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.
What is the use of a bimetallic strip in a thermostat?
The 2 metals have different coefficients of expansion so when the strip heats up it bends. This bending is arranged to separate an electrical connection so that the electrical power causing the heating is switched off, and then back on again when things cool back down slightly.
How bimetallic strip works?
Scroll down to related links and look at "Bi-metallic strip - Wikipedia".
How does a bimetallic strip act as a switch?
It acts as a switch in thermostats because it starts curved and when it cools down enough for it to straighten up it touches another piece of metal, completing a circuit before bending again due to the heat. Hope this helped!

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.
