WATER

Water is the most important ingredient for life mean to say life is impossible without water. Frequent use of water keeps us healthy and fresh and do our daily tasks in a mire better way. Many of the people are unaware of the proper way of drinking water as this thing may cause harm to our body so always drink water as recommended by the biology.


Roughly 70 percent of an adult’s body is made up of water. At birth, water accounts for approximately 80 percent of an infant’s body weight. Drinking too much water too quickly can lead to water intoxication. Water intoxication occurs when water dilutes the sodium level in the bloodstream and causes an imbalance of water in the brain. Water intoxication is most likely to occur during periods of intense athletic performance.

Water dissolves more substances than any other liquid. Wherever it travels, water carries chemicals, minerals, and nutrients with it. Soft drinks, coffee, and tea, while made up almost entirely of water, also contain caffeine. Caffeine can act as a mild diuretic, preventing water from traveling to necessary locations in the body. Pure water (solely hydrogen and oxygen atoms) has a neutral pH of 7, which is neither acidic nor basic.

Somewhere between 70 and 75 percent of the earth’s surface is covered with water. The total amount of water on the earth is about 326 million cubic miles of water. Of all the water on the earth, humans can used only about three tenths of a percent of this water. Such usable water is found in groundwater aquifers, rivers, and freshwater lakes.

CLOUDS

                Clouds are made up of millions of tiny droplets of water, which are formed when moist warm
air rises up into the sky and is then cooled down. The water that makes clouds comes from the earth. Clouds make rain and rain falls down on the ground. Black clouds make snow or rain.
               Clouds can make rain and they can make thunderstorms and they can make beautiful pictures. Sometimes clouds look like they are sheets floating in the air, or sometimes they look like big fluffy ice-cream cones. The role of clouds in regulating Earth's temperature and climate has still not been fully understood by scientists.
                Cirrus clouds are made up of ice droplets and look like thin, wispy streaks or curls. They are the
highest clouds in the sky and usually bring a change of weather. Cumulus clouds are the ones that look like fluffy balls of cotton, or scoops of ice-cream all piled up. These clouds indicate fair weather is coming. Stratus clouds are clouds that look like great sheets pulled across the sky. These are the type of clouds that are closest to the ground and may bring rain or drizzle. Most clouds are named for their shapes. Clouds form when warm, moist air hits cold air.

IS IT EASY TO LIFT A HEAVY STONE IN WATER?

                        It is true. The heavy stone will weigh much less in water. As much less as the weight of water it displaces. The law governing this is known as the Archimedes principle.
