Although it can be destructive, radioactivity is also beneficial, especially when it comes to medical tests and certain medical treatments. Not only can radiation find tumors within the body, it can also destroy them or slow their growth. Without radiation, society would not have medical imaging technology, such as X-rays. Radiation also makes it possible to study matter, plants and animals in an effort to understand the universe better.Know More
Radiation can also be used to create electrical energy. Nuclear reactor plants are located all over the country for this purpose. These plants use uranium in fission reactions to produce heat and steam. The steam is then used to turn a turbine, thus creating electricity.
Additionally, radiation can be used to clean and sterilize medical equipment, medical instruments and even food. This is accomplished by focusing concentrated beams on objects that need to be sterilized. The radiation kills bacteria and other organisms that cause contamination and disease. Since sterilization is performed using certain types of radiation along with electromagnetic energy, there is no residual radiation leftover to contaminate the objects.
While radiation has many benefits, too much of it can kill people, animals, plants, trees and any other living thing it comes into contact with on Earth. This is especially true if there is prolonged exposure.Learn more about States of Matter
Irene Joliot-Curie and her husband Frederic were both nuclear physicists who experimented with the manipulation of elements, particularly as it related to their radioactivity. Her crowning achievement came in 1936 with the discovery that radioactive isotopes could be created from otherwise stable elements.Full Answer >
Solids are defined as substances that retain their shape, even when they are not confined. Substances usually assume the solid state of being at lower temperatures than they do when they are liquids, gases or plasmas.Full Answer >
According to Crayola, crayons begin to soften at 105 degrees Fahrenheit and melt at a temperature range of 120 to 147 degrees F. The melting range for all standard Crayola crayons is identical.Full Answer >
The phase of chlorine is dependent upon temperature and pressure, but it is a gas at room temperature and standard pressure. At standard pressure, chlorine liquefies at minus 29.15 degrees Fahrenheit and freezes at minus 149.76 degrees Fahrenheit.Full Answer >
