The mass of an empty density bottle is 30g. When filled with a liquid, the mass reduces to 38g. Calculate the apparent cubic expansivity of the liquid
-
A.
6.25 x 10K-1 -
B.
6.25 x 10-3K-1 -
C.
2.50 x 10-3K-1 -
D.
2.50 x 10-4K-1
Correct Answer: Option B
Explanation
Apparent cubic expansivity = (frac{text{mass of hot liquid expelled}}{text{mass of hot liquid left x temp. rise}})
= (frac{2}{8 times 40} = 0.00625)
