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.

What household appliance could a bimetallic strip be used?
A bimetallic strip could be used in a thermostat, where it can bend and complete or break an electrical circuit to regulate temperature.
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.
The element in a thermostat that is sensitive to temperature changes is what?
The element in a thermostat that is sensitive to temperature changes is typically a bimetallic strip. This strip is made up of two different metals that expand and contract at different rates in response to temperature variations, causing the strip to bend and activate the thermostat's switch.
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 much does a bimetallic strip cost?
The cost of a bimetallic strip can vary depending on the size, material, and manufacturer. On average, a bimetallic strip can range from a few dollars to tens of dollars.
What is a use of a bimetallic strip in everyday life?
thermostat

What happens when bimetallic strip is heated?
The bimetallic strip bends.
Which gadgets use the bimetallic strip?
fire alarm
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.
