A relative density bottle of volume 50cm³ is completely filled with a liquid at 30^oC. It is then heated to 80^oC 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

Correct answer is A

Ya = \(\frac{\text{Vol. expelled}}{\text{Vol. left x temp. change}} = \frac{0.75}{49.25 \times 50}\)

= 0.00030k^-1
