What are the sources of thermal pollution? Some of the important sources of thermal pollution are nuclear power and electric power plants, crude oil refineries, steel melting factories, coal fire power plant, boiler from industries which release large amount of heat to the water bodies leading to change in the physical, chemical and biological characteristics […]

What happens to current during charging and discharging of a capacitor?
What happens to current during charging and discharging of a capacitor? Ans: During the process of charging the capacitor, the current flows towards the positive plate (and positive charge gets added to that plate) and away from the negative plate. While during the discharging of the capacitor, current flows away from the positive and towards […]
How is cubical expansion calculated?
How is cubical expansion calculated? “VOLUMETRIC EXPANSION ” or “CUBICAL EXPANSION”. Consider a metallic body of volume = V1 . Let it’s temperature is raised by T. then experimentally “Increase in volume ( V) is directly proportional to its initial volume (V1) and rise in temperature ( T). What is an example of anomalous Behaviour […]

Why does the outer shape of our earth keep on changing?
Why does the outer shape of our earth keep on changing? The Earth’s shape changes because the climate events like El Nino shift where the mass of water is stored: in oceans, continents and the atmosphere. What are 4 processes that shape Earth’s surface? Explanation: The four common Planet Surface Processes are: Cratering, Volcanoes, Erosion, […]
Why does high pressure bring clear weather?
Why does high pressure bring clear weather? The absence of wind in high pressure is due to the lack of an air-pressure gradient. Because rising air cools and results in the condensation of water vapor, which is the reason for clouds and precipitation, downward-moving air and high pressure usually brings mostly clear skies. What is […]
