Thermal power plants are one of the main sources of electricity in both industrialized and developing countries. These plants have drawn flak on consumption of non-renewable sources of energy at a rapid rate and also since they release huge amounts of greenhouse gases into the atmosphere. The anti-greenhouse gas activists are calling for thermal power to be replaced by other cleaner sources of energy. Functioning of thermal power plant: In a thermal power plant‚ one of coal‚ oil or natural gas

Linear Thermal Expansion The term thermal expansion refers to the increase in size of an object as that object is heated. With relatively few exceptions‚ all objects expand when they are heated and contract when they are cooled. Perhaps the most important exception to this rule is water. Water contracts as it cools from its boiling point to about 39.2°F (4°C). At that point‚ it begins to expand as it cools further to its freezing point. This unusual effect explains the fact that ice is less dense

effect that the concentration of a solue has on the conductivity of an electrolytic solution. If NaCl is added to water to create an electrolytic solution then it will create a stronger electrical current than distilled water because NaCl is a strong electrolyte that can conduct electricity well due to its ability to dissociate into ions. Materials and Methods: In order to test for the effect that the concentration of a solute has on the conductivity of an electrolytic solution. Four beakers were filled

GASEOUS DISCHARGE LAMPS: A gaseous discharge lamp is essentially a glass or quartz envelop containing two electrodes and a small quantity of gas or vapour at a low pressure. In these lamps light is obtained by applying an electric potential difference to a gas or vapour contained by the lamp under a suitable pressure. Due to application of electric potential difference gas gets ionised and an electric current flows; the tube is filled with a luminous discharge. The light spectrum
