Question

statement (1): The linear expansion does not depend on the nature of the material, initial length, and rise in temperature.
statement (2): The coefficient of linear expansion depends on the nature of the material and system of temperature.

• A. statement 1 and statement 2 are correct and statement 2 is correct explanation for statement 1
• B. statement 1 and statement 2 are correct and statement 2 is not correct explanation for statement 1
• C. statement 1 is true and statement 2 is false
• D. statement 1 is wrong and statement 2 is true

Answer 1

The correct option is D statement 1 is wrong and statement 2 is true

Since linear expansion depends on the coefficient of linear expansion and coefficient of linear expansion depends on the nature of the material, a rise in temperature.
Therefore, statement 1 is wrong but statement 2 is a correct statement
