Which of the following materials has the highest coefficient of linear expansion?
a) Glass
b) Steel
c) Aluminum
d) Copper



Answer :

Answer:

c) Aluminum

Explanation:

The coefficient of linear expansion is a measure of how much a material expands per unit length per degree change in temperature. It is a property that varies from material to material.

The material with the highest coefficient of linear expansion among the options provided is:

c) Aluminum

Aluminum has a higher coefficient of linear expansion compared to glass, steel, and copper. This means it expands more for a given increase in temperature.
