A liquid with coefficient of volume expansion γ is filled in a container of a material having the coefficient of linear expansion α. If the liquid over flows on heating : (a) γ = 3α (b) γ > 3α (c) γ < 3α (d) γ > 3α3 |

On account of the coefficient of cubical expansion of liquid γ is more, equal and less than the cubical expansion of the metal of container. Hence, when liquid is heated, it will overflow so that cubical expansion will be greater than 3α.</span></span></p> | |
