Solid has maximum density and liquid has a low density as compared to solid. So the state which has low density floats and with high density they shrink.Complete answer:Ice is solid so it floats on water because water molecules expand on freezing and form an open cage-like structure. This leads to a decrease in the density of ice. This means for a given mass ice will have more volume as compared to liquid water. Thus, being lighter ice floats on water.A] solid have lesser density than liquid- solids have a high density as compared to that of liquid, so this option is not correct B] it has open – cage-like structure in which fewer molecules are packed per mL than water – when water freezes it expands and formed a cage-like structure so this option is correct C] ice is lighter than water – it is incorrect as ice is lighter than water but when it forms a cage-like structure D] when ice is formed water molecules come closer and start floating – water molecules come closer but due to this density does not decrease. So this option is incorrectOur correct option is ‘B’ it has an open – cage-like structure in which fewer molecules are packed per mL than water.Note:-Solid are highly rigid but gases are not rigid -Solid has negligible compressibility but gases have high compressibility -Solids have a definite shape but gases do not have a definite shape-Solids have the least kinetic energy gases that have maximum kinetic energy.-Solids do not flow as gases flow in all directions.Recently Updated PagesMaster Class 9 Social Science: Engaging Questions & Answers for SuccessMaster Class 9 Science: Engaging Questions & Answers for SuccessMaster Class 9 English: Engaging Questions & Answers for SuccessMaster Class 9 Maths: Engaging Questions & Answers for SuccessMaster Class 11 Economics: Engaging Questions & Answers for SuccessMaster Class 11 English: Engaging Questions & Answers for SuccessMaster Class 9 Social Science: Engaging Questions & Answers for SuccessMaster Class 9 Science: Engaging Questions & Answers for SuccessMaster Class 9 English: Engaging Questions & Answers for SuccessMaster Class 9 Maths: Engaging Questions & Answers for SuccessMaster Class 11 Economics: Engaging Questions & Answers for SuccessMaster Class 11 English: Engaging Questions & Answers for Success
