Acid Rain

Acid Rain is a specific form of precipitation which is acidic. It has elevated levels of hydrogen ions. It can harmful effect on plants aquatic animal, infrastructure. Acid Rain occurs when certain emissions come into contact with the water of the atmosphere. Learn everything about it in this article and info graphic. it is a precipitate in any of the following forms  Rain  Snow  Sleet  fog Which contains high level of acid which are  Sulfuric acid Nitric acid Which are the constituent of following  70% derived from oxydation and hydrolysis of Sulfur die oxide and hydrogen sulfide. 30% derived from various nitric oxides and other compounds. Both Sulphur and nitrogen emission attributed to the burning of the fossil fuels. Last …

Refrigerator & Pressure cooker working

Refrigerators and air conditioners both work on the principle of cooling through evaporation and as the pressure rises, the temperature of the water and steam inside the sealed pot (the pressure cooker) also rises above the normal 100ºC (212ºF) boiling point temperature. Refrigerator & Pressure Cooker Refrigerator & Pressure Cooker Refrigerator When inside the fridge temperature reaches to 0 degree centigrade then there is no need to cool it further . So, the thermostat cut the signal and cuts the power to compressor to stop its cooling function. When we open it in a closed room room will be more temperate. Pressure Cooker PRINCIPLE– The basic principle of pressure cooker is cooking under increased pressure. We know that when water is heated to 100 degee centigrate it begins …

Water Colour Purity

In this article of Water Colour & Purity, we will see scientifically about the colour of water, the spherical shape of a liquid drop, the colour of a waterfall and at last the purity of water. Water Colour Purity Water is transparent and nearly colourless liquid. Waterdrop is spherical because the liquid drop tends to be in a state of minimum surface area. Reason of Spherical shape of the water drop is the force. It is Surface tension that try to hold the droplet together. Mathematically, sphere has the smallest surface volumes, compared to other geometric shapes. In absence of the external force liquid always want to attain minimum surface area and got spherical shape. Waterfall When all colour gets reflected …

Vehicle Emission

Vehicle Emission is human-made Problem and human can control it. So, you very well know what is vehicle emission. in this article, First I will discuss a problem. What is Vehicle Emission ? The Pollutants emitted from an automotive engine during the combustion process is known as vehicle emission. During the process of it mainly 3 gases are emitted which are as following Carbon mono oxide (CO) Hydrocarbon (HC) Oxide of nitrogen (NOx) These gases are very harmful which is coming from our vehicles. if there are many vehicles in the area many pollution present there and every gas causes different deceases. Back PainDaily News Analysis Why Vehicle Emission is harmful? It is harmful because it emits harmful gases for the environment which …
