Why do chips gain mass in salt solution? When the chips were put in distilled water they gain mass because the chips gain water from the surrounding solution due to osmosis. The process of osmosis causes a net flow of water across the semi permeable membrane, from a solution with a high water concentration to […]
What is physical process and chemical process?
What is physical process and chemical process? There is no real difference between a chemical process and a physical process in chemistry. According to such teachers, things like burning fuels are chemical processes and things like dissolving salt in water or freezing water into ice are physical processes. What are the physical features of Earth? […]
What size is a photon?
What size is a photon? In this way you could say the “size” of photon is basically the width of its wavelength. The wavelength of green light is about 500 nanometers, or two thousandths of a millimeter. The typical wavelength of a microwave oven is about 12 centimeters, which is larger than a baseball. How […]

What are the 3 assumptions of science?
What are the 3 assumptions of science? Understanding science: scientific assumptions Nature is orderly, and the laws of nature describe that order. We can know nature. All phenomena have natural causes. Nothing is self evident. Knowledge is derived from acquisition of experience. Knowledge is superior to ignorance. Do scientists make assumptions? All scientific tests involve […]

What do you mean by real and virtual image?
What do you mean by real and virtual image? A real image is the collection of focus points actually made by converging rays, while a virtual image is the collection of focus points made by extensions of diverging rays. In other words, it is an image which is located in the plane of convergence for […]
What is the advantage of main switch?
What is the advantage of main switch? The major advantage of using a main switch is that it can break the connection of both, the live and the neutral wire at the same time. This protects electrical appliances from accidental damage due to electrical faults. Why do live wires connect to switches? The switch must […]
What tissue sends messages from brain to body?
What tissue sends messages from brain to body? Neuron. Neurons allow the brain and body to communicate by relaying sensory information and motor commands as electric signals. The most complex workings of the nervous system depend on messages sent through neurons. Together with their support cells, neuroglia, neurons make up all nervous system tissue. How […]
