What is condensation GCSE Bitesize?
Cooling. If water vapour (gas) is cooled down, it changes into water (liquid). This change is called condensation.
What is evaporation GCSE?
Evaporation is when a liquid is heated and changes state into a gas. When a solution is heated, some of the solvent evaporates, leaving behind a saturated solution – one in which no more solid can dissolve at that temperature. The saturated solution is allowed to cool and crystals to form.
Why is the water cycle important GCSE?
All living organisms need water. Some can survive in a dormant state without it for long periods of time, but all organisms will eventually die without it. Water is constantly recycled. Energy from the Sun evaporates water from the land and sea forming water vapour.
What is the water cycle GCSE?
The water cycle is also known as the hydrological cycle. It describes how water moves on, above, or just below the surface of our planet. Water molecules move between various locations – such as rivers, oceans and the atmosphere – by specific processes. Water can change state .
What is evaporation explain?
Evaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles “disappear” on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing—it is evaporating into a gas, called water vapor. Evaporation happens on a global scale.
How does evaporation cause the cooling of water GCSE?
During evaporation, the liquid particles at the surface get heated and start vibrating at a greater amplitude. These particles move into a gaseous phase as the bond between them and the rest of the liquid breaks. This reduces the average energy possessed by the liquid and thus causes a cooling effect.
What is water cycle condensation?
Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds.
What are the main events of the water cycle?
The water cycle consists of three major processes: evaporation, condensation, and precipitation.
What is condensation explain?
Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
What are two differences between evaporation and condensation?
By definition, evaporation is a process where water changes into vapour. Condensation is the opposite process where water vapour is converted to tiny droplets of water. Evaporation occurs before a liquid reaches its boiling point. Condensation is a phase change regardless of the temperature.
What is evaporation and condensation?
This change is called evaporation. If water vapour (gas) is cooled down, it changes into water (liquid). This change is called condensation. Regenerators: Green Classroom!
How does condensation occur in gases?
Condensation involves a gas changing to a liquid. The particles in a gas have a range of different energies. Some may not have enough energy to remain as separate particles, particularly if the gas is cooled down. They come close together and bonds form between them.
What is condensation and why is it important?
Condensation is the process by which water vapor is changed back into liquid water. Condensation is very important to our weather and climate because it is what is responsible for cloud formation. Without clouds, we would not get to the third phase, called precipitation, which we will talk about in a minute.
What happens to the temperature of a liquid during evaporation?
Once a high energy particle has escaped the remaining particles in the liquid will then have a lower average kinetic energy than before, so the temperature of the liquid will be lower than before – the liquid cools down as evaporation happens.
