 From small airplanes like the Cessna to large twin-engine jets like the Airbus A380, all combustion-powered airplanes require fuel to operate. Like combustion-powered automobiles, they burn fuel to create the power needed to achieve and maintain a safe flying speed. While there are several types of aviation fuel, though, most consist of kerosene. So, why do airplanes use kerosene rather than plain gasoline for fuel? Kerosene has a lowering freezing point than gasoline, making it naturally protected against freezing in otherwise bone-chilling temperatures. But regardless, it takes cooler temperatures for kerosene to freeze than it does for gasoline to freeze. In addition to a lower freezing point, kerosene has a higher flash point than gasoline. Flash point refers to the temperature at which a combustible chemical or substance ignites and turns to vapor. With its higher flash point, kerosene offers higher octane ratings to achieve greater power and efficiency when compared to its gasol

Alcohol. It can be just the buzz we need on a night out or a cozy evening in. But how does alcohol get you drunk? Why do our bodies and brains react in the way they do when alcohol enters our systems? We sip from the cup of truth, with a chaser of science. In your mouth, alcohol mixes with saliva and enters your bloodstream through tiny blood vessels. Your stomach and small intestine absorb more alcohol into your bloodstream once it reaches them. Alcohol dilates your blood vessels. This causes that feeling of warmth. Your brain releases serotonin and dopamine to make you feel good. Your kidneys make and release a whole bunch of pee. This brings down the water levels in your body, increasing alcohol concentration. Alcohol vapor diffuses from your blood into your lungs. Your liver breaks alcohol down into water and carbon dioxide, making you feel less drunk. Factors like age, sex, and body weight can also affect how drunk you feel after consuming booze. Ethanol is the key ingredient in a
