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

KINETICS OF THE ACID DECOMPOSITION OF THIOSULFATE Aqueous solutions of thiosulfate‚ S2O32-(aq) are stable if neutral or basic‚ but decompose quickly when the thiosulfate is dissolved in acid according to the equation: Sulfur dioxide is a gas at room temperature‚ but is very soluble in water. Sulfur‚ a water insoluble solid‚ forms a colloidal suspension. As a result‚ the solution first becomes cloudy and then opaque. We can take advantage of the developing opacity of the reaction system to do a

THERMAL INSULATION MATERIALS Thermal insulation materials are specifically designed to reduce the heat flow by limiting heat conduction‚ convection‚ radiation or all three while performing one or more of the following functions: The main function of insulation is to reduce the heat transfer‚ the insulation material must have the appropriate characteristic to slow down the transport of heat occurred by conduction‚ convection and radiation. Conduction loss in insulation is negligible. There are

Factors affecting the catalytic decomposition of Hydrogen peroxide Please refer to the additional files for tables/graphs. Aim- The purpose of this investigation is to investigate how certain factors affect the catalytic decomposition of Hydrogen peroxide. I will investigate the effect of altering the mass of catalyst used on the rate of the decomposition of Hydrogen peroxide. Introduction- The decomposition of Hydrogen peroxide is a process by which Hydrogen peroxide decomposes into water and

Measuring the enthalpy change of vaporisation of water You should attempt this part of the activity even if you have not seen the demonstration of the practical. 1. Calculate a value for ∆Hvap for water in KJ mol-1 using the data from the demonstration. Also‚ calculate ∆Hvap from the following data gathered by a student; 8100 J were needed to distil 2.95g of water. a) Explain why the boiling tube was surrounded with expanded polystyrene (or other similar insulation)‚ but the condenser was left

Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation

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

Ocean Thermal Energy Conversion SPH3U I. Introductory Covering over 70% of the earth ’s surface‚ water is one of the most amazing energy sources. From olden times‚ people had previously utilized the force of the waters in order to crush grain or help them to do their work more efficiently. Since then as a power source‚ water draws a lot of attention due to the efficient manner in which it gets to produce electricity. Ocean Thermal Energy Conversion (OTEC) is a method introduced in
