What is Schottky defect with diagram? A Schottky defect is an excitation of the site occupations in a crystal lattice leading to point defects named after Walter H. In ionic crystals, this defect forms when oppositely charged ions leave their lattice sites and become incorporated for instance at the surface, creating oppositely charged vacancies. Why […]
What happens in the upper mantle?
What happens in the upper mantle? The upper mantle begins just beneath the crust and ends at the top of the lower mantle. The upper mantle causes the tectonic plates to move. Crust and mantle are distinguished by composition while the lithosphere and asthenosphere are defined by a change in mechanical properties. Why is the […]
What is another name for the extrusive rock?
What is another name for the extrusive rock? volcanic rocks What are the classification of igneous rock? As has already been described, igneous rocks are classified into four categories, based on either their chemistry or their mineral composition: felsic, intermediate, mafic, and ultramafic. What are some examples of an igneous rock? These rocks include: andesite, […]
What is the relationship between vapor pressure and temperature?
What is the relationship between vapor pressure and temperature? The vapor pressure of a liquid varies with its temperature, as the following graph shows for water. The line on the graph shows the boiling temperature for water. As the temperature of a liquid or solid increases its vapor pressure also increases. Conversely, vapor pressure decreases […]

What methods are used in primary treatment of wastewater?
What methods are used in primary treatment of wastewater? There are three basic biological treatment methods: the trickling filter, the activated sludge process, and the oxidation pond. A fourth, less common method is the rotating biological contacter. What is the main goal of primary treatment in a modern sewage treatment plant? The objective of primary […]
Can you craft force of nature?
Can you craft force of nature? The Force-A-Nature is automatically given to any player who obtains 10 Scout achievements…. Force-A-Nature Giftable: Yes Nameable: Yes Craft No.?: No Medieval: No How much damage does the force of nature do? Force-a-Nature deals 10% less damage, so 3-10.5 minus 10% equals 2.7-9.45 damage per pellet. It also fires […]
What are the main function of vascular bundles?
What are the main function of vascular bundles? Functions of Vascular bundles: Xylem transport the water absorbed by roots to the leaves, whereas the phloem transport food materials form leaves (photosynthetic products) to all part of the plants including roots. Vascular bundles also provides mechanical support (a mechanical tissue) to the plant. What is the […]
Does equilibrium constant depend on pressure?
Does equilibrium constant depend on pressure? Equilibrium constants are not changed if you change the pressure of the system. The only thing that changes an equilibrium constant is a change of temperature. If there are the same number of molecules on each side of the equation, then a change of pressure makes no difference to […]
