Question

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

Answer 1

Explanation:

Apparent expansion coefficient of liquid when heated in Copper vessel = C

Coefficient of linear expansion of copper= A

Apparent expansion coefficient of liquid when heated in silver vessel = S

Liquid expansion coefficient = x (say)

Solution:

For copper,

C= x -3A ( volume expansion = 3 × linear expansion)

For silver,

S =x - 3α

Ag

Since liquid expansion coefficient is same,

C+ 3A = S+ 3α

Ag

⇒C+3A−S=3α

Ag

⇒α

Ag

=

3

C+3A−S

Hence, B is the correct option.

Correct option is

B

3

C+3A−S
