Properties Of Solids And Liquids Question 413

Question: The apparent coefficient of expansion of a liquid when heated in a copper vessel is C and that when heated in a silver vessel is S. If A is the linear coefficient of expansion of copper, then the linear coefficient of expansion of silver is

Options:

A) C+S3A3

B) C+3AS3

C) S+3AC3

D) C+SA3

Show Answer

Answer:

Correct Answer: B

Solution:

[b] γr=γa+γv

where γr = coefficient of real expansion, γa= coefficient of apparent expansion and γv=

coefficient of expansion

From copper: γr=C+3αcu=C+3A

For silver, γr=S+3αAg

C+3A=S+3αAgαAg=CS+3A3
