Temperature is a measure of energy. Adding energy to a substance makes it hotter; removing energy makes it colder. Warm, energetic molecules move faster and farther, spreading out over a larger volume of space. This balloon has been cooled to hundreds of degrees below zero (Fahrenheit), condensing the gas molecules inside. At room temperature, the

 Everyone knows that on Thanksgiving you eat lots of turkey and it makes you sleepy somehow…except that it probably doesn’t. There is a lot of information out there about this subject, and much of it seems to disagree with itself. Let’s examine the whole idea from the beginning. Courtesy of Rutgers University It all

The Speed of Fire
The Speed of Fire

How fast is fire? We sent a burst of flame through a fluorescent light tube to explore the propagation of an alcohol-burning reaction along an enclosed path. In our experiment, the frontier of flame sped along at over six feet per second. Fire behaves very differently in other environments. In space, combustion becomes almost unrecognizable.

Electricity is one element of physics that we encounter on a daily basis. It powers our televisions and our computers, and keeps the lights on at home. Magnets are something we think of as less common, only using them when we need to navigate using a compass or stick something to our fridge. But electricity

Earth’s gravitational force pulls on all objects equally, speeding them up with an acceleration of 32 feet per second per second. This means after one second of falling, an object will speed up to 32 feet per second, or about 22 miles per hour. After two seconds, that will double to 64 feet per second
