How does the concept of linear expansion help the fabrication of bimetallic strips Explain the working g of bimetallic strips in a thermostats?
The concept of linear expansion is used in bimetallic strips to create a temperature-sensitive component. Bimetallic strips are made by bonding two different metals with different coefficients of thermal expansion. When exposed to temperature changes, the metals expand or contract at different rates, causing the strip to bend. In a thermostat, this bending action controls an electrical switch, regulating the temperature by turning a heating or cooling system on and off.

Explain why a bimetallic strip is used in a rotary thermometer instead of a strip with only one kind of metal.?
A bimetallic strip is made from two different metals that expand at a different rates. Two strips of these metals are bonded together, and when the temperature changes, one side expands more than the other, forcing the bimetallic strip to curl (the longer side would be on the outside of the curl). So if one end is clamped, the other moves. This motion is used to turn the dial of the thermometer.
How would you use Thermal expansion in a sentence?
Example sentence - Our homework assignment is to give an example of thermal expansion and explain why it happens.
What is thermal expansion and explain its two types?
Thermal expansion is the tendency of a material to change in volume, length, or area in response to a change in temperature. The two main types of thermal expansion are linear expansion, where an object grows in length in one dimension, and volumetric expansion, where an object expands in all dimensions.
What do you mean by real expansion and apparent expansion of liquid Describe an experiment to explain the fact?
The real expansion of a liquid refers to its actual increase in volume due to temperature change, whereas apparent expansion includes factors like the expansion of the container. An experiment to demonstrate this could involve filling a narrow-necked glass bottle with colored water, sealing it, and then heating it. The liquid will rise and the apparent expansion will be visible due to the liquid level surpassing the original bottle capacity. To differentiate between real and apparent expansion, repeating the experiment with a tube attached to allow the liquid to expand freely and observing the difference in volume change would be beneficial.
Explain how the common thermometer works by expansion?
A common thermometer works by using a liquid like mercury or colored alcohol that expands when heated and contracts when cooled. This expansion and contraction is used to measure temperature changes and is visualized through a scale on the thermometer, which gives a reading based on the level of liquid inside.
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.
