In this article, we'll find out what causes rip currents, how you can recognize them and what you should do if one takes you out to sea. A rip current is a narrow, powerful current of water running perpendicular to the beach, out into the ocean. These currents may extend 200 to 2,500 feet (61 to 762 m) lengthwise, but they are typically less than 30 feet (9 m) wide. Rip currents can move at a pretty good speed, often 5 miles per hour (8 kph) or faster.

So, if you are measuring in Kelvin, twice as cold is not possible. (0/2=0) However, if you are using the Celsius scale, zero degrees is actually 273.15Â° above absolute zero. So, twice as cold would be -136.575Â° Celsius. Similarly, absolute zero in Fahrenheit is -459.67Â°. Thus, from zero degrees F, twice as cold would be -229.835Â° F.
