(c) Aluminium is a highly reactive metal, yet it is used to make utensils for cooking. Order of decreasing reactivity – B > A > C > D. Mineral: The naturally occurring compounds and elements are known as a mineral. Steam and iron were linked as early as 1722 when Darby, an iron magnate, and Newcomen worked together to improve the quality of iron for producing steam engines. Answer: In the cases we'll be looking at on this page, the phases will simply be the solid, liquid or vapour (gas) states of a pure substance. Name two metals which will displace hydrogen from dilute acids, and two metals which will not. Question 3. Lets first see some basic information about boilers.

Steam For the supply of dry steam with no entrained condensate at a stable pressure To control pressure even from a location that is physically distant from the pressure reducing valve For compact steam-heating equipment For steam transport lines, heaters, etc. A steam engine is a heat engine that performs mechanical work using steam as its working fluid.The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. gallium and caesium. This drying equipment can also perform batch or continuous processing of the wet feed. It is commonly formed by boiling or evaporating water. An Ellingham diagram guides the partial pressure of oxygen required for a particular type of oxide formed on a metal.
