Condensation

- Condensation is a process by which a substance changes from a gaseous state to a liquid state. As a gas cools, it loses heat, or thermal energy. The particles that make up the gas move more slowly; that allows the attractive forces among them to increase, causing droplets of liquid to form.

Oct 13, 2022 · When condensation happens inside your home, there are three main factors that contribute to the formation of water droplets. These include: The humidity of indoor air – As we touched on...
A simple way to form a drop is to allow liquid to flow slowly from the lower end of a vertical tube of small diameter. The surface tension of the liquid causes the liquid to hang from the tube, forming a pendant.

- What Causes The Air to Rise?
Many people believe that clouds are just made of water vapour (a gas). However, this is not strictly true. Water vapour is invisible, and it is around us all the time in the air. Sometimes there is more water vapour in the air and it feels humid or muggy. Other times, the air has less water vapour and it feels drier and fresher. Clouds appear when ...
As a simple explanation, when air rises, it cools, much like when you are going up a mountain and the air tends to get colder. Cold air can’t hold as much water vapour than warm air can, so as the air cools, it becomes saturated and the water vapour in it condenses. This means it turns from a gas to a liquid, much like when you get condensation on ...
1. The sun– The sun heats the ground, which then heats the air just above it, causing it to rise upwards in the sky (warm air rises). This tends to produce cumulus clouds. 2. Hills and mountains- When air is travelling towards a mountain or hill, it cannot go into the hill and so it rises upwards along the terrain. Stratus clouds are often produced...
Jun 8, 2019 · Depending on weather conditions, water molecules will combine with tiny particles of dust, salt, and smoke in the air to form cloud droplets, which combine and grow, developing into clouds, a form of water we can see.
Apr 25, 2013 · Cold surfaces can cause water vapor in the air to cool down, condense and form tiny beads of liquid. The molecules in these miniscule droplets of water are grouped far more closely together...

7.2: Nucleation of Liquid Droplets. Nucleation (the creation of new droplets) in clean air is called homogeneous nucleation (Fig. 7.4a). We will show that homogeneous nucleation is virtually impossible in the real atmosphere and can be neglected.
