How many different types of batteries are there?

How many different types of batteries are there? three types What is the main function of a battery? A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The […]

What material expands the most when heated?

What material expands the most when heated? By contrast, iron, with a coefficient of 1.2, is 24 times more likely to expand or contract as a result of changes in temperature. (Steel has the same value as iron.) The coefficient for aluminum is 2.4, twice that of iron or steel. Which state of matter contracts […]

What are three primary methods of monitoring volcanic activity?

What are three primary methods of monitoring volcanic activity? Volcanologists use many different kinds of tools including instruments that detect and record earthquakes (seismometers and seimographs), instruments that measure ground deformation (EDM, Leveling, GPS, tilt), instruments that detect and measure volcanic gases (COSPEC), instruments that determine how much lava is … How can we detect […]

What are the harmful effects of photochemical smog?

What are the harmful effects of photochemical smog? Harmful effects of photochemical smog: It corrode metals, stones, rubber and painted surface. It causes serious health problems to senior citizens, children and people with heart and lung problems which lead to emphysema, bronchitis, asthma. What are the negative environmental and health impacts of smog? Smog can […]

What is the angle between the two vectors?

What is the angle between the two vectors? “Angle between two vectors is the shortest angle at which any of the two vectors is rotated about the other vector such that both of the vectors have the same direction.” Furthermore, this discussion focuses on finding the angle between two standard vectors, which means their origin […]

How can you classify mixture?

How can you classify mixture? Mixtures can be classified on the basis of particle size into three different types: solutions, suspensions, and colloids. The components of a mixture retain their own physical properties. These properties can be used to separate the components by filtering, boiling, or other physical processes. Can you still recognize salt from […]

What is photosynthesis answer in one line?

What is photosynthesis answer in one line? Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules. […]
