Answer:
The bimetallic strip will bend to the iron's way since
When heated copper expands more than iron
Explanation:
bimetallic strips are temperature regulatory devices used to convert a temperature change into mechanical displacement.
It consists of two layers, usually iron and copper which layers are joined together to form the strip owing to the difference in the constants of expansion of the two materials, a flat strip will bend one way (toward the iron part) if heated. The linear thermal expansion coefficient relates the change in temperature to the change in a material's linear dimensions.
A reaction between two pure solids is very rare. For a reaction to occur, the molecules must interact with each other. Since molecules of solids are very compact, they don't have the liberty to collide with one another. However, this is made possible by hydrates of solids. An examples would be CuSO₄·5H₂O. In this case, they have a an intermediate liquid to react them together.
Answer:
i have no clue i just need brailnly points
Explanation:
Answer:
The body may be changing its direction due to which velocity get zero because velocity is the distance covered by an object in some time and in a particular direction.
Answer: 384,300,000 m
