exothermic process surroundings

Matter In Our Surroundings - Summary Matter - anything which has mass, occupies space and can be perceived by our senses. Law of conservation of matter - matter can neither be created nor destroyed. The states of matter are solid, liquid gas, plasma and super cooled solid. The three main ..

Combustion Process - Combustion is a chemical reaction in which burning of substances takes place. In this process, a substance combines with oxygen to burn (decompose) itself liberating heat and sometimes light and flame. Thus, combustion reactions are exothermic or h..

Combustion is a chemical reaction in which burning of substances takes place. In this process, a substance combines with oxygen to burn (decompose) itself liberating heat and sometimes light and flame. Thus, combustion reactions are exothermic or heat dissipating reactions. Burn..

Isothermal process is that in which the temperature of the system remains constant. Adiabatic process is where there is no exchange of heat between the system and the surrounding. Isobaric process is when the pressure on the system remains constant during an..

Numerous bars of wrought iron surrounded by carbon are heated in fire-brick boxes to a temperature of around 1000 o C for 10 days. The carbon diffused slowly into iron and converts iron into steel. Carbonisation of the iron bars is obviously more at the surface. This results in blis..

An isochoric process is a constant-volume process. When the volume of a thermodynamic system is constant, it does zero work on the surroundings. Then W = 0, and In an isochoric process, all the energy added as heat remains in the system as an increase in inte..

>converter . Here the preheated mixture of sulphur dioxide and air form sulphur trioxide. As the reaction is exothermic, the catalyst is heated in the beginning and the temperature is maintained by the heat evolved during the reaction. Initially it is heated to about 450 o C. This is the ..

It is a well-known fact that all physical and chemical processes are accompanied by energy changes. It is possible to interpret various spontaneous processes on the basis of changes in energy. Consider the spontaneous processes such as falling of a cricket ball from o..

Ammonia can be synthesized from nitrogen and hydrogen in accordance with the reaction. The equilibrium constant of this reaction may be written as, ..

During the manufacture of sulphuric acid (Contact process), sulphur trioxide is prepared by the oxidation of sulphur dioxide in accordance with the reaction,..
