A relative density bottle of volume 50cm3 is completely filled with a liquid at 30oC. It is then heated to 80oC such that 0.75cm3 of the liquid is expelled. Calculate the apparent cubic expansivity of the liquid.

0.00030k-1
- 0.00032k-1
- 0.01970k-1
- 0.02030k-1
The correct answer is: A
Explanation
Ya = \(\frac{\text{Vol. expelled}}{\text{Vol. left x temp. change}} = \frac{0.75}{49.25 \times 50}\)= 0.00030k-1
