What are two examples of an endothermic reaction? These examples could be written as chemical reactions, but are more generally considered to be endothermic or heat-absorbing processes: Melting ice cubes. Melting solid salts. Evaporating liquid water. Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes. What are some real life […]

What is the principle of an electric?
What is the principle of an electric? The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force. What is the working of motor? An electric motor is an electrical […]
Can resistant bacteria be cured?
Can resistant bacteria be cured? Antibiotics won’t help either, because a virus causes these illnesses. The best way to treat your cold is to manage the symptoms. Save the antibiotics for strep throat or a sinus infection. What happens if antibiotics don’t work? When bacteria become resistant, the original antibiotic can no longer kill them. […]

How much energy is recovered by regenerative braking?
How much energy is recovered by regenerative braking? When the conventional vehicle brakes, the energy is lost to heat energy resulting from the friction between the brake pads and wheels. Regenerative braking allows the range of the EV to be extended; however, the efficiency of capturing this energy is reported to vary from 16% to […]
Which type of material may be classified as either soft or hard?
Which type of material may be classified as either soft or hard? Magnetic materials are further classified as soft or hard according to the ease of magnetization. What is difference between hard and soft material? Those materials which cannot be easily compressed, cut, bent or scratched are called hard materials. Examples: Iron, glass. Those materials […]

What is the two main types of chemical bonds?
What is the two main types of chemical bonds? Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Why do all bonds form? Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer […]
