The mass of an empty density bottle is 30g. When filled with a liquid, the mass of the bottle and the liquid is 40g. On heating the filled bottle through 40ºc, the mass reduces to 38g. Calculate the apparent cubic expansivity of the liquid
6.25 x 10K-1
6.25 x 10-3K-1
2.50 x 10-3K-1
2.50 x 10-4K-1
Correct answer is B
Apparent cubic expansivity = \(\frac{\text{mass of hot liquid expelled}}{\text{mass of hot liquid left x temp. rise}}\)
= \(\frac{2}{8 \times 40} = 0.00625\)
