introductory video on condensation and evaporation. Take students on a nature walk and ask the students to locate examples of condensation and evaporation.
These learning experiences link with the following content descriptors:
“Science involves making predictions and describing patterns and relationships (ACSHE050)” (Australian Curriculum and Assessment Reporting Authority [ACARA], 2016).
Lesson 2 Explore: Hands on activity, explore the concept or skill. Make sense of the concept or skill (this may take more than 1 lesson and be combined with explore) Use ice cubes and a heat lamp to explore the…
Purpose: We already knew that the chemical properties of each pure substance are not are not changed after separation in a mixture. The key to find a physical property that one part of the mixture does have but the parts of the mixture doesn’t. In magnetism a magnetically susceptible material is extracted from a mixture depending on a magnetic force. Filtration is separation of an insoluble solid and a liquid. Filtration depends on solubility, the filtrate is the one want to keep (liquid) and…
How does the Earth’s Water Cycle works?
The water cycle is a process in which Earth’s water never stops moving by three steps evaporation, condensation and precipitation. Water is if not the most one of the most important components of life. Water defines how most ecosystems are. The water cycle is also connected by several ways to every other system in Earth.
What is the water cycle? Water in Earth is always in movement, but how does it move. The water cycle also known as the hydrological…
After this happens it starts to condense and cool the land into rain or snow into clouds. Now I am going to tell you a few things about the four main process in the water cycle on the Earth. The first type is called Evaporation, this happens from heat from the sun causes natural water features to evaporate and turn from liquid to gas and then it rises into the sky. This water vapor in the sky starts to form clouds. The second type is called Condensation this happens as water vapor from the…
disk. Condensation and evaporation are represented in this model. The warm water evaporated. Condensation formed inside the jar and under the lid of the jar. The component that is found in the disk is ice that is melted. The water cycle processes represented is evaporation .This model could be altered to include all of these processes unless there were additional specimens and additional testing possibly using soil, plants, ice, water, and a larger jar . The weather would be affected if the…
Evaporation Model, Kohler modification and Surface Phenomena
The process of microdroplet evaporation is associated with the mass and heat transport through the microdroplet surface [1,2] .
Where a is the droplet radius, Pa and Pcc are the saturated vapor pressures near the droplet surface and far from the droplet respectively. Ta and Tcc are the temperatures at the microdroplet surface and the reservoir. D is the diffusion constant of vapor in the ambient gas. M and are the…

These two rules have made different forms of successful distillation in many locations around the world. Multi-Stage Flash distillation (MSF) is the process that accounts for the most desalination capacity. There are also two similar processes but less commonly used: Multiple Effect Distillation (MED) and Vapor Compression Distillation (VC). These processes can explains as follows:

In the Middle East Multi-stage flash (MSF) plants are widely used…
transpiration and evaporation, (About Evapotranspiration, 2016).” the location of the project is the broken down hydroelectric station in a weir in proximity of the camp, information supplied by EWB. Due to this there is a nice rectangular cemented area providing easy access. The principal of the solution is having a steel cooler vaccine box lowered to the weirs depths where the water temperature is at its coolest. The project shall use only native materials of the area or from other towns in…
Purpose: The objective is to separate the heterogeneous mixture of salt, iron filings, and salt into each pure form using filtration, evaporation, and magnetism.
When separating a mixture, preferably to separate a mixture that includes a soluble liquid and a insoluble solid, filtration is the best because solid molecules are bigger than liquid molecules. A filter contains pores that are small enough to let small partials though the pores while holding back the larger particles.…
