heat zone areas

Along with warmer temperatures and higher humidity, the number of very hot days is expected to rise in many areas around the globe. Heat stress occurs in such conditions and the young, old and poor people are more susceptible to it. High temperatures will reduce work efficiency..

. But, the actual result shows anomaly. This was not explained at that time. However, Planck propounded quantum theory in 1905. Einstein applied it to specific heat problem in 1907. Ultimately, Debye was successful in 1912, in fully explaining the thermal behavior of metals and non-metals..

When a metal sheet of rectangular shape is heated, its length is increasing at 2 cm per second and width at 3 cm per second. Find the rate of change of its area, when its length is 14 cm and width is 12 cm? => 26 cm 2 /sec or 42 cm 2 /sec or 66 cm 2 /sec or 64 cm 2 /sec or 24 cm..

Biosphere Reserves - The concept of biosphere reserves has been evolved by UNESCO's Man and Biosphere Programme (MABP). A biosphere reserve is a specified area in which multiple use of the land is permitted by dividing it into zones, each for a particular activit..

Biome is a large, regional or sub continental biosystem characterized by a major vegetation type or other distinct landscape characters such as tropical deciduous forest, tundra biome, etc. "The major terrestrial ecosystems (largest ecological units) of distinctive terrestrial areas with ..

Expansion in area of a Laminar surface due to heating is known as superficial expansion. Let a 1 = area of a surface t 1 = its initial temperature a 2 = area of the surface after heating t 2 = final temperature The coefficient of superficial expansi..

The space between soil particles on the surface of earth is called pore space. It is of two types - micro and macro pores. Most of the water is held in micro pores. Pores, which are available for plant roots. Surface soil pore spaces are generally filled with air and water. Water that per..

Plants absorb water through the entire surface - roots, stems and leaves. However, mainly the water is absorbed by roots. The area of young roots where most absorption takes place is the root hair zone. The root hairs are delicate structures which get continuously replaced by n..

When a solid is in the form of a Lamina, its length and breadth increase on heating. Hence, its area also increases. This is known as superficial expansion. Area of Laminar body increases on heating..
