Industrial Chemical Processes Essay Tan Hung Kai Grade 11 In our present world‚ there are thousands of chemical processes that are being used to produce products that benefits our daily lives. Industrial Chemical processes are used for “transforming raw materials into useful commercial products for society”. (Dr. Philip Britz-Mckibbin Industrial Chemistry: CHEM 2013) Examples of industrial chemical processes include distillation‚ smelting‚ disinfection‚ and Pyro processing. Even today‚ scientists

placed the fluted filter paper into a funnel‚ the mud was placed into the top. The funnel was then placed on to a conical flask. After some time the mud will filter through in the form of a liquid. This is then put into a evaporation dish. Then the dish placed this evaporation dish on top of the tripod over a lit Bunsen burner on the blue flame. After a short amount of time turn the Bunsen burner off leaving approximately 15ml. Then‚ the mummion has to be left until white crystals form in the

CHLORIDE‚ SODIUM CHLORIDE‚ SAND the wt. of mixture with evaporating dish after 1st heating is?? g. And after Its 2nd heating?? g. The method used to separate that mixtures are Filtration and Evaporation. Filtration is the process of separating the solid from the liquid by using a porous filter. And Evaporation is the process of reducing the volume of a solution. The substances that separated are the sand and the salt. What is the purpose of adding water to the residue (the solid particles that remained

and then the clear water is poured into another container. Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. The other type of vaporization is boiling‚ which‚ instead‚ occurs within the entire mass of the liquid and can also take place when the vapor phase is saturated‚ such as when steam is produced in a boiler. Evaporation that occurs directly from the solid phase‚ as commonly observed

first one i will be talking about. It is a continuous cycle and the water goes from liquid state to a gas state over and over again. It begins in a process called evaporation which is “the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.” After it goes through evaporation begins to condensate. Condensation is “water that collects as droplets on a cold surface when humid air is in contact with it.” Condensation happens on the outside

premised on the notion that if scientists can find signs of water on any planet in our universe‚ then there is the possibility of life‚ such as mars. a.What are the most considerable impacts you make? We know how the heat from the Sun leads to evaporation through rays on the oceans and seas. When water evaporates to form clouds‚ these clouds will then in turn form into rain. The rain falls and helps plants to grow and eventually to form more mists and clouds and rain‚ the cycle continues. If water

water uptake occurs‚ water is then moved up through the plant via the xylem. When the water reaches the leaves evaporation occurs‚ the water forms a meniscus between the mesophyll cells and the lower pressure potential in this meniscus allows for the evaporation to occur. This evaporation creates a force that pulls water up the plant (Carrier). The stomata control the rate of evaporation and the absorption of CO2. Transpiration have many factors that can affect how fast transpiration can occur‚ temperature

lake to another‚ just like from an ocean to the atmosphere. Water travels by different processes of evaporation‚ condensation‚ precipitation‚ infiltration‚ runoff and subsurface flow. When these processes occur water goes through different phases such as: liquid‚ solid and gas. Hydrologic cycle involves the exchange of heat energy‚ which leads to temperature changes. The process of evaporation where water takes up energy from the surroundings and cools the environment‚ however in the process of
