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.Know More
Clouds, fog and the "sweat" that builds up on the outside of a glass with a cold drink are all examples of condensation. Molecules in the gaseous state have a more random arrangement than those in a liquid state. As the vapor pressure builds, the gas molecules are forced into a more structure arrangement. The slowing in motion leads to a release of heat, which drops the temperature even further.
As condensation continues, the water droplets adhere to one another. In a situation where someone's reading glasses are fogging up, the process stops fairly quickly. In a large cloud, the process continues, in many cases, often to the point where precipitation begins. The water at the bottom of a cloud begins to fall, sending water further on its way around the water cycle.Learn More
The boiling point of distilled water is 100 degrees Celsius or 212 degrees Fahrenheit. The boiling point of water can be higher or lower depending on several factors.Full Answer >
A bonfire built with wood and charcoal can burn at temperatures up to 2,012 degrees Fahrenheit. The color of the fire is an indicator of temperature; dark red flames are cooler at 1,112 degrees F than orange-yellow flames at 2,012 degrees F.Full Answer >
The boiling point for pure water is 212 degrees Fahrenheit and the melting point is 32 degrees. Pressure and the purity of the water can have an impact on the melting and boiling point.Full Answer >
Common water is non-flammable, non-explosive, non-radioactive and not biologically hazardous. Water does not have a low specific heat. Water does not have a low surface tension or a low evaporation rate at 70 degrees Fahrenheit.Full Answer >
