Smoking Water Vapor: Are E-Cigarettes Safe?

From patches and gum to hypnosis and acupuncture, there are so many methods to quit smoking. The newest method, however, combines a smoker's need for nicotine with the physical habit of holding and smoking a cigarette. This new device is called an electronic cigarette, often shortened to e-cigarette. Instead of inhaling harmful chemical-laced tobacco, however, users are smoking water vapor. How exactly does this work, though? And is it even safe?...(more)

Identifying Weak Electrolytes

Chemical compounds can be categorized in various ways. One of these is according to their electrical properties. Compounds that increase the conductivity of water in solution are called electrolytes. Electrolytes can be broken down, in turn, into weak and strong electrolytes. While weak electrolytes break down into ions only partially when mixed with water, strong electrolytes ionize nearly completely. Being able to distinguish a weak electrolyte from a strong electrolyte or a nonelectrolyte is critical to experiment planning, not to mention safety in the laboratory....(more)

Understanding Ultraviolet Radiation

Ultraviolet radiation is a form of energy that comes primarily from the sun. It is a potentially damaging form of energy, and the reason people get tanned or sunburned if they spend too much time outdoors. In order to understand this radiation, it is important to understand how it works. Things like wavelength and energy level can impact how dangerous a particular form of radiation is, and what you need to do to protect yourself from it. Read on to learn more about what ultraviolet radiation is, its effects, and how you can keep yourself safe....(more)
