Which will help you to get higher marks in Physics subject. These Mcqs are useful for students and job seekers i.e MCAT ECAT ETEA test preparation, PPSC Test, FPSC Test, SPSC Test, KPPSC Test,BPSC Test, PTS ,OTS,GTS,JTS,CTS.

IF YOU THINK THAT ABOVE POSTED MCQ IS WRONG.

###### 20 Comments to “The co efficient of linear expansion is equal to__________?”
1. Sidra khalid says:

Option b is correct because alpha is equal to the expression in option b..
Option A s incorrect because it is the final expression for change in length due to expansion.

B is correct.

3. Inam Ullah Khan says:

Co-efficient of linear expansion is equal to delta L divided by L delta T. The answer here is wrong because the given answer for change in length.

4. The co efficient of linear expansion is equal to__________?
Answer is Delta L is divided by L delta T. Alpha is the co-efficient of linear expansion, so correct it. Answer mark by you is for Only linear expansion is equal to delta L = alpha L delta T.

5. Inam Ullah Khan says:

B is the right answer for the question. The marked answer is wrong due to what it says about the change in length.

1. Tayyaba says:

2. Fouzià bhangwar says:

Yes b is right ans because question is ask about co efficient of leaner expansion

3. Syed Saifullah Ansari says:

B is the right answer, the question is about the coefficient of linear expansion not linear expansion so, correct answer is B

B is correct ans

7. Amara Gandapur says:

They are asking about coefficient of linear expension , which is Alpha ….so B answer is correct .

8. Laraib says:

9. Ayesha says:

I think B is right

10. Akhtar Zaman Anjum says:

@=◇L/L◇T

Coefficient of linear thermal expansion = change in length per original length per degree rise in temperature.

The right answer of coefficient of linear expansion is b option cuz they are asking about that coefficient is equal to

12. Yasar Ali MPhil Scholar says:

Linear Expansion = Change in Length / (Original Length) (Change in Temperature)

13. Option A is 100% wrong
Option B is right

14. ZAKIR says:

correct option is B

15. Siddique says:

B is the right option.
Ais the standard form equation that shows the relation

16. Naresh says:

Coefficient of linear thermal expansion (Alfa)=∆L/L∆T

17. Syed Saifullah Ansari says:
