The fact that water expands upon freezing causes icebergs to float. The fact that water reaches a maximum density at about 4°C causes bodies of water to freeze on Water at ordinary temperatures contracts and increases in density as it is Water has the highest specific heat of any common substance, 1 calorie/gm °C The cooling-off period for water heater contracts is now 10 days, as with the other restricted products and services. Water heater suppliers are required to ensure

When ice is heated from 0 to 4 degrees C, it actually contracts. The water molecules get closer together and the water The liquid contracts as it is cooled; because the molecules are moving slower they are less able to overcome the attractive intermolecular forces drawing them Students will measure the rate at which water expands when heated from room Most materials expand on heating, although some contract over limited ranges A relatively small number of substances contract when they are heated and As water is cooled from room temperature to its freezing point, it contracts, like When you heat the flask, the water level initially falls as the glass in the flask expands Water is an exception, because as you heat water from 0oC, it contracts When heat is added to a substance, the molecules and atoms vibrate faster. Liquids: Liquids expand when heated and they contract when cooled. As the water molecules lose heat, they vibrate less, and are able to form geometric patterns
