PPT-Aseel Samaro Dissolving and evaporating

Gemstones such as amethyst are crystal that formed deep in the Earths crust Water dissolved salts and as this solution cooled over thousands of years the precious crystals formed Introduction. Exploring gas pressure. The pressure of the atmosphere is not the same in all places – it varies with height.. High up a mountain the atmospheric pressure is much lower than at sea level.. In space there is no atmosphere and so there is no pressure.. Investigating the effectiveness of . antacids . Introduction. Heartburn indigestion is caused by acid from the stomach irritating the upper digestive . tract.. For . those who suffer regularly, treatments are available to . Understanding how seeds are dispersed by the wind . The largest seed in the world is 50 cm in . diameter.. It . comes from the palm tree called Coco de . Mer. , found only in the Seychelles islands in the Indian . Exploring the movement of water and minerals in plants. Water is needed in cells to support the plant and to . photosynthesise. . Minerals in the soil dissolve in water.. How do plants get the water and minerals they need? How do they move through the plant?. Exploring the importance of minerals to plants. All plants require essential elements that are not supplied by photosynthesis – minerals that are found in soil and absorbed by the plant through its root system.. Exploring reactions of acids with carbonates . Introduction. Some rocks, such as limestone, contain a metal carbonate – limestone contains calcium carbonate. . Limestone . reacts with acids in a predictable way, and as new products are formed the limestone is eroded..

Special consideration should be given to Exploring Magnets. Magnets have many effects, sometimes surprisingly strong.. They have many uses including computer hard drives, loudspeakers, credit card strips, magnetic fasteners and compasses for navigation.. Understanding . challenges . facing pollinators . It a scanning electron micrograph (SEM) of a pollen basket of a worker honey bee. Worker bees go from flower to flower collecting nectar and pollen to feed the colony. Changing . Physical state. When you make ice or melt the frost from a windscreen, you are making use of changes of . state.. What . is actually happening to the particles in these processes?. Introduction. Separating mixtures. If you put different objects together, such as different fruits in a bowl, toys in a box or sweets in a bag, you have a . mixture.. Simply . picking out one object separates it from the . Exploring the role of stomata. Plants are found in a huge range of habitats.. In order to . photosynthesise. , plants need a supply of carbon dioxide.. How do plants get carbon dioxide? Why does oxygen, a product of photosynthesis, not build up in the leaf?. Dissolving Compounds. For . a substance to dissolve, . solute-solvent . attractions must overcome the . attractions . within both solute and solvent. . Example: In order to dissolve, ionic bonds must be broken by water. . . Transmission Basics - Aseel AlHadlaq. Data vs Signal. Data – information formatted in human/machine readable form . examples: voice, music, image, file . Signal – electric or electromagnetic representation of data .
