Water is a liquid at room temperature because the hydrogen bonds within its construction are weak. These weak bonds hold water molecules together for mere milliseconds, which keeps water in a constantly liquid state at room temperature.Continue Reading
Room temperature is defined as anywhere from zero to 100 degrees Celsius. In other temperatures, water can also be a gas or a solid. Water becomes a gas when the hydrogen bonds that form molecules move quickly. Water becomes a solid, or frozen, when the molecules are slowed down. Water changes easily between its three forms.
To change from a gas to liquid requires the process of condensation. A liquid-to-solid transformation is known as freezing, and a solid-to-gas transformation is known as sublimation. During this process, water changes from ice to water vapor. The changing of water from liquid to gas is known as evaporation.
This process is easily performed by watching the level of water go down as a pot boils on a stove. If the water is left to boil unattended, at some point the pot is emptied of water. The change from a solid to a liquid is known as melting, such as when ice thaws in the spring. Water also rarely changes from a gas directly to a solid, known as the process of front formation.Learn more about States of Matter
The process of a gas changing to a liquid is called condensation, and for condensation to take place, the environment has to reach maximum vapor pressure, generally through a lowering of temperature in the case of the water cycle. Because pressure varies inversely with temperature, as temperature decreases, pressure goes up, causing the gas molecules to move with progressively less kinetic energy. Eventually, liquid vapor and droplets form, and the gas begins to condense.Full Answer >
The phase of chlorine is dependent upon temperature and pressure, but it is a gas at room temperature and standard pressure. At standard pressure, chlorine liquefies at minus 29.15 degrees Fahrenheit and freezes at minus 149.76 degrees Fahrenheit.Full Answer >
Mercury, the only metal that remains liquid at room temperature, is more than 13 times denser than water. One way of comparing densities of liquids is by combining them to determine which floats on top of the other. However, some liquids dissolve in water, making this method unreliable. Creosote and sulfuric acid are both denser than water, but sulfuric acid is an aqueous solution that mixes with water.Full Answer >
When water is at room temperature, its density is 998.23 kg/m3, which is only slightly less than the normal density of water at exactly 1000 kg/m3. The density of water is dependent on the temperature.Full Answer >
