Question on: WAEC Physics - 2014
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
Ask EduPadi AI for a detailed answer
Correct Option: B
Apparent cubic expansivity = \(\frac{\text{mass of hot liquid expelled}}{\text{mass of hot liquid left x temp. rise}}\)
= \(\frac{2}{8 \times 40} = 0.00625\)
= \(\frac{2}{8 \times 40} = 0.00625\)
