Whenever a liquid is heated in a container, expansion in liquid as well as container takes place. If r is the volume expansion coefficient of liquid and is coefficient of liner expansion. Match the entries of Column I and Column II Column IColumn II(i) Liquid level rises with respect to container(A) g=2a(ii) Liquid level remains same with respect to container(B) 2α<γ<3α(iii) Liquid level drops with respect to container(C) g=3a(iv) Liquid level remains same with respect to ground(D) g>3a
