Question

How does the original length of a brass rod and increase in its temperature affect the
Iinear expansion of the rod on being heated?​

Answer 1

Answer:

Explanation:

As observed the relationship of the change in length and change in temperature of a body is directly proportional. It suggests that as the body experience heat, the atoms become excited dispersing and expands thus increases the length or size of an object.When materials are heated, their size and volume increase in small increments, in a phenomenon known as thermal expansion. Expansion values vary depending on the material being heated. The coefficient ratio of thermal expansion indicates how much a material expands per 1℃ (2.2℉) rise in temperature.
