What is the difference solution and suspension? 1. Solutions are mixtures that are homogeneous while suspensions are mixtures that are heterogeneous. 2. The particles of a solution are at the ion or molecular level and cannot be seen by the naked eye while the particles of a suspension can be seen by the naked eye. […]
Why are steam burns more serious than burns caused by an equal amount of equally hot water?
Why are steam burns more serious than burns caused by an equal amount of equally hot water? Steam is more likely to cause burn injuries than boiling water because of the latent heat of vaporization. Since water expands to approximately 1,600 times its volume when it turns from liquid to steam, steam often escapes its […]
What type of microscope do doctors use?
What type of microscope do doctors use? Electron microscopes use concentrated beams of electrons and dyes to illuminate their specimens. These electron beams have very short wavelengths, which means they are able to produce exceptionally high-resolution images. Clinics can utilize these scopes to identify and examine viruses within the bloodstream. How can a microscope be […]
How Does drinking water help your joints?
How Does drinking water help your joints? Water helps to keep your joints lubricated and flexible; the Synovial fluid that directly lubricates your joints is made up primarily of water. This fluid reduces the friction between joints and helps to maintain healthy tissue and joints. Can drinking more water help arthritis? If there’s a magical […]
What happens when the air temperature and the dew point are very far apart?
What are the 5 different types of reactions?
What are the 5 different types of reactions? The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. What are 10 indicators of a chemical change? Bubbles of gas appear. Gas-producing reactions run to completion when the gas can leave the reaction mixture. A precipitate forms. A color change occurs. The […]
What is the ratio of calcium to fluoride ions?
What is the principle of DC generator *?
What is the principle of DC generator *? DC generator operates on the principle of the dynamically induced electromagnetic force. When a conductor is placed in a varying magnetic field, an electromotive force gets induced within the conductor. This induced e.m.f magnitude is measured using the equation of the electromotive force of a generator. What […]
Is Colour change a physical or chemical property?
Is Colour change a physical or chemical property? Color. The changing of color of a substance is not necessarily an indicator of a chemical change. For example, changing the color of a metal does not change its physical properties. However, in a chemical reaction, a color change is usually an indicator that a reaction is […]
Why do electrons have spin?
Why do electrons have spin? Because electrons of the same spin cancel each other out, the one unpaired electron in the atom will determine the spin. There is a high likelihood for either spin due to the large number of electrons, so when it went through the magnetic field it split into two beams. What […]
