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.

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.
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.
Which two metals are used in bimetallic strip?
Commonly, brass and steel are used in a bimetallic strip. This combination allows the strip to bend or warp when subjected to temperature changes due to the different thermal expansion coefficients of the two metals.
What is a bimetallic strip and where can it be used?
A bimetallic strip is made of two different metals bonded together, which have different coefficients of thermal expansion. This causes the strip to bend when heated or cooled. Bimetallic strips are often used in thermostats, temperature switches, and circuit breakers to control temperature-sensitive mechanisms.

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 happens when bimetallic strip is heated?
The bimetallic strip bends.

Is bimetallic strip is used in spoon?
A bimetallic strip is not typically used in spoons. However, bimetallic strips can be found in devices such as thermostats, thermometers, and switches due to their ability to bend when exposed to temperature changes, which can be used to control electrical circuits.
How could a bimetallic strip be used to help you perform a parctical task in everyday life?
A bimetallic strip can be used in a thermostat to control the temperature of a heating or cooling system. When the temperature changes, the different expansion rates of the two metals in the strip causes it to bend, activating or deactivating the heating or cooling system accordingly. This helps maintain a desired temperature in a room.
