Detailed explanation-1: -Water is the only common substance that is naturally found as a solid, liquid or gas. Solids, liquids and gases are known as states of matter.
Detailed explanation-2: -Water is a liquid at room temperature, but becomes a solid (called ice) if it is cooled down. The same water turns into a gas (called water vapor) if it is heated up. The changes only happen when the substance reaches a particular temperature. Water turns to ice at 32ºF (0ºC).
Detailed explanation-3: -Water can exist in solid, liquid and gaseous forms at different temperature conditions. The solid form of water is ice, the gaseous form is water vapour and the regular water that we use is in liquid form.
Detailed explanation-4: -Under standard atmospheric conditions, water exists as a liquid. But if we lower the temperature below 0 degrees Celsius, or 32 degrees Fahrenheit, water changes its phase into a solid called ice.
Detailed explanation-5: -Water can exist in three states: solid (ice), liquid, and gas (vapor). Even other substances can also exist in 3 different states depending upon the temperatures. Example: oxygen and carbon dioxide.
