Solution
The correct option is AC+3A−S3 Given:
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)
