<\/p>\n
Some materials expand on heating and some contract on cooling. Heating makes the particles (that form the material) expand or become loose. Cooling makes the particles (that form the material) contract or become tight.<\/p>\n
The amount of expansion differs in solids, liquids, and gases. Gases expand the most while solids\u00a0expand the least. Table shows some examples of expansion.<\/p>\n
\n Expansion in solids<\/strong><\/p>\n<\/td>\n Expansion in gases<\/strong><\/p>\n<\/td>\n<\/tr>\n Railway tracks consist of two parallel metal rails joined together. Small gaps, called expansion gaps, are deliberately left between the rails as there is an expansion of the rails in hot weather.<\/p>\n <\/p>\n<\/td>\n If you keep an inflated balloon in the sun for some time, what will happen? It will grow in size as the air inside it expands on taking heat from the surroundings.<\/p>\n <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Cooling does the opposite of heating. Cooling causes a material to contract. Solids contract the least while gases contract the most. Table lists some examples of contraction.<\/p>\n Contraction in solids<\/strong><\/p>\n<\/td>\n Contraction in gases<\/strong><\/p>\n<\/td>\n<\/tr>\n If we hold a very hot glass tumbler under cold water, it cracks. This is because the outer surface of the glass comes in direct contact with cold water and contracts more as compared to the inner surface.<\/p>\n <\/p>\n<\/td>\n <\/td>\n If an inflated balloon is tied at the mouth of a bottle and the bottle is placed in ice-cold water, what will happen? The balloon will shrink in size, as the air inside the balloon contracts on cooling.<\/p>\n <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Expansion by heating can be used in several everyday activities.<\/p>\n Expansion and Contraction in Solids, Liquids and Gases Some materials expand on heating and some contract on cooling.
