When you add a salt to ice with a little bit of water, the salt lowers the freezing point of the water, keeping it from re-freezing as easily and helping to melt the rest of the ice. Thomas Northcut, Getty Images If you live in an area with a cold and icy winter, you have probably experienced salt on sidewalks and roads, used to melt the ice and snow and keep it from refreezing. Salt is also used to make homemade ice cream. In both cases, the salt works by lowering the melting or freezing point of water. The effect is termed freezing point depression'. How Freezing Point Depression Works When you add salt to water, you introduce dissolved foreign particles into the water. The freezing point of water becomes lower as more particles are added until the point where the salt stops dissolving. For a solution of table salt (sodium chloride, NaCl) in water, this temperature is -21°C (-6°F) under controlled lab conditions. In the real world, on a real sidewalk, sodium chloride ...

Why doesn't vodka freeze when you put it in the freezer? The answer to the question has to do with the chemical composition of vodka and a phenomenon known as freezing point depression. The Chemical Composition of Vodka Mendeleeve, the chemist who devised the periodic Table, standardized the amount of ethyl alcohol (ethanol) in vodka when he was the Director of the Russian Bureau of Standards. Russian vodka is 40% ethanol and 60% water by volume (80 proof). Vodka from other countries may range from 35% to 50% ethanol by volume. Ethanol and Freezing Point Depression When you dissolve any liquid in water, you lower the freezing point of the water. This phenomenon is known as freezing pint depression. It is possible to freeze vodka, but not in a typical home freezer. The freezing point of 80 proof vodka is -26.95° C or -16.51° F, while the temperature of most home freezers is around -17° C.

BANANAS: GOOD INFORMATION     A professor at CCNY for a physiological psych class told his class about bananas.  He said the expression "going bananas" is from the effects of bananas on the brain.  Read on: Never, put your banana in the refrigerator!!! This is interesting. After reading this, you'll never look at a banana in the same way again. Bananas contain three natural sugars - sucrose, fructose and glucose combined with fiber. A banana gives an instant, sustained and substantial boost of energy. Research has proven that just two bananas provide enough energy for a strenuous 90-minute workout. No wonder the banana is the number one fruit with the world's leading athletes. But energy isn't the only way a banana can help us keep fit. It can also help overcome or prevent a substantial number of illnesses and conditions, making it a must to add to our daily diet. Depression: According to a recent survey undertaken by MIND amongst people ...

  How much water do you need a day?                                           Water is an important structural component of skin cartilage, tissues and organs. For human beings, every part of the body is dependent on water. Our body comprises about 75% water: the brain has 85%, blood is 90%, muscles are 75%, kidney is 82% and bones are 22% water. The functions of our glands and organs will eventually deteriorate if they are not nourished with good, clean water.                   The average adult loses about 2.5 litres water daily through perspiration, breathing and elimination. Symptoms of the body's deterioration begins to appear when the body loses 5% of its total water volume. In a healthy adult, this is seen as fatigue and general discomfort, whereas for an infant, it can be dehydrating. In an elderly person, ...
