# On heating a liquid of efficient of cubical expansion ' r ' in a container having coefficient of cubical expansion $\;\large\frac{r}{3}\;$ , the level of liquid in the container will

$(a)\;rise\qquad(b)\;fall\qquad(c)\;remain\;the\;same\qquad(d)\;difficult\;to\;say$

Explanation :
Since expansion of liquid is more than expansion of container .
