Isothermal Lines
Isothermal Lines The “isothermal process”, which is thermodynamic process in which the temperature of a system remains constant. The transfer of heat into or out of the system happens so slowly that thermal equilibrium is maintained. “Thermal” is a term that describes the heat of a system. “Iso” means “equal”, so “isothermal” means “equal heat”, which is what defines thermal equilibrium. In general, during an isothermal process there is a change in internal energy, heat energy, and work, even though the temperature remains the same. Something in the system works to maintain that equal temperature. One simple ideal example is ... Read more
Housing in India
Housing in India Issues related to housing sector in India Un-planned growth of settlements A number of housing clusters have mushroomed in and around various metropolitan centres in haphazard and unplanned manner, without a proper layout and devoid of service lines and other essential facilities. These unauthorized developments are encroachments on land parcels belonging to Govt. bodies, public- private-institutions or areas meant to be green belts. The removal/ re-settlement of these overcrowded un-hygienic clusters, commanding massive vote banks, is a serious challenge to correcting these aberrations for a planned growth of cities, especially in our democratic set-up? Therefore, massive concerted ... Read more
Spherical Coordinates and Projections,Time
Spherical Coordinates and Projections,Time Spherical coordinates can be a little challenging to understand at first. Spherical coordinates determine the position of a point in three-dimensional space based on the distance ρ from the origin and two angles θ and ϕ. If one is familiar with polar coordinates, then the angle θ isn’t too difficult to understand as it is essentially the same as the angle θ from polar coordinates. But some people have trouble grasping what the angle ϕ is all about. Relationship between spherical and Cartesian coordinates Spherical coordinates are defined as indicated in the following figure, which illustrates ... Read more
World Climate:- Climate and seasons, distribution of rain fall and climatic regions
World Climate:- Climate and seasons, distribution of rain fall and climatic regions Climates and seasons Different parts of the world have different climates. Some parts of the world are hot and rainy nearly every day. They have a tropical wet climate. Others are cold and snow-covered most of the year. They have a polar climate. Between the icy poles and the steamy tropics are many other climates that contribute to Earth’s biodiversity and geologic heritage. Climate is determined by a region’s climate system. A climate system has five major components: the atmosphere, the hydrosphere, the cryosphere, the land surface, and ... Read more

Urbanisation
Introduction Urban areas have been recognized as “engines of inclusive economic growth”. Of the 121 crore Indians, 83.3 crore live in rural areas while 37.7 crore stay in urban areas, i.e approx 32 % of the population. The census of India, 2011 defines urban settlement as :- All the places which have municipality, corporation, cantonment board or notified town area committee All the other places which satisfy following criteria : A minimum population of 5000 persons At least 75 % of male main working population engaged in non-agricultural pursuits A density of population of at least 400 persons ...

Energy Resources
Sources of Energy: Conventional and Nonconventional Sources –
Energy is one of the most important component of economic infrastructure. It is the basic input required to sustain economic growth. There is direct relation between the level of economic development and per capita energy consumption. Simply speaking more developed a country, higher is the per capita consumption of energy and vice-versa. India’s per capita consumption of energy is only one eighth of global average. This indicates that our country has low rate of per capita consumption of energy as compared to developed countries.
Two Main Sources ... Read more
