Do Gas Stations cause soil pollution? Soils are extremely important parts of every ecosystem. They are a home to many microbes and provide vital nutrients to the plants that live in them. pH is the measure of acidity or alkalinity of a solution‚ and most organisms have a very small range of pH values in which they can survive. 7 is considered neutral‚ lower than 7 is acidic (lemon juice‚ rain water) and above 7 is basic (bleach‚ soap). Lots of urban areas are dependent on car transportation‚

Travelling by trains is cheap and comfortable compared to buses and planes. So we find a railway station a place of great hustle and bustle. We come across people from different parts of the country‚ in different fashions and colours in the station. Once I happened to be at the Old Delhi Railway Station to see off my friend. He was going to Kolkata by the Kalka Mail. The waiting hall was fully crowded with passengers. There was a long queue in front of the booking window. Everyone seemed to

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

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

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

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
