Question

Consider the following statements
1. The coefficient of linear expansion has dimension [k-1]
2. The coefficient of volume expansion has dimension [k-1]

a. 1st and 2nd Both are correct
b. 1st is correct and 2nd is wrong
c. 1st is wrong and 2nd is correct
d. 1st and 2nd Both are wrong​

Answer 1

Answer:

a is correct because ratio of length is in linear expansion and ratio of volume is in cubical expansion which will cut each other to give K^-1

Answer 2

Answer:

The both of the given statements are true.

Explanation:

• When heat is applied to certain materials it happens to increase the dimensions of those solids to which the heat is applied.
• There are different ways some expand volumetrically and others expanding area some expand length and breadth and with the expansion comes the coefficient of linear and volumetric expansion.
• So, both the linear and volume expansion are having the same co-efficient dimension.
