What is the difference between IR and FTIR? FTIR spectrometers have several prominent advantages: (1) The signal-to-noise ratio of spectrum is significantly higher than the previous generation infrared spectrometers. (2) The accuracy of wavenumber is high. Due to these advantages, FTIR Spectrometers have replaced dispersive IR spectrometers. What is the principle of IR spectroscopy? IR […]
When two or more solid substances are mixed together they liquefy is called?
When two or more solid substances are mixed together they liquefy is called? In chemistry, a mixture is a material system made up of two or more different substances which are mixed but are not combined chemically. A mixture refers to the physical combination of two or more substances in which the identities are retained […]
How is energy transferred from one object to another?
How is energy transferred from one object to another? The two ways that energy can be transferred are by doing work and by heat transfer. Can an object have work? In the physics sense, work is never something an object has. It is only something that one object does to another. Work changes the amount […]
Is forced hot air unhealthy?
Is forced hot air unhealthy? The biggest downside of using a forced air heating system is that it leaves you vulnerable to inefficiency stemming from ductwork problems. If your ductwork is well-designed, expertly installed, and kept in prime condition, then you’ll be able to heat your home quite efficiently. Is forced air heating cheaper? Other […]
What is the wavelength of an ocean wave?
What is the wavelength of an ocean wave? Spectrum Wave type Typical wavelength Disturbing force Capillary wave < 2 cm Wind Wind wave 60–150 m (200–490 ft) Wind over ocean Seiche Large, variable; a function of basin size Change in atmospheric pressure, storm surge Seismic sea wave (tsunami) 200 km (120 mi) Faulting of sea […]
What is the largest body of water on Earth?
What is the largest body of water on Earth? Pacific Ocean What are the four bodies of water? There are five classifications of bodies of water: Oceans, seas, lakes, rivers, and canals. There are 5 oceans: Atlantic, Pacific, Indian, Arctic, and Southern. They are salt water and cover 2/3 of the earth’s surface. Seas are […]
Which is the least reactive metal?
Which is the least reactive metal? Silver, gold, and platinum are metals with the least reactivity. They are found in nature. Which is a very reactive metal? Caesium Which is more reactive platinum or gold? The more reactive the metal, the more rapid the reaction is. Platinum is placed below gold in the reactivity series. […]
How many homes can 1 GW power?
What is all matter made up of?
What is all matter made up of? Explain that all matter on Earth exists in the form of a solid, liquid, or gas, and that solids, liquids, and gases are all made of extremely tiny particles called atoms and molecules. Tell students that an atom is the smallest building block of matter and a molecule […]
What are the 3 major layers of the geosphere?
What are the 3 major layers of the geosphere? The Earth’s geosphere is divided into three chemical sections: The crust, composed almost entirely of light elements, like silicon. The mantle, which is 68% of the Earth’s mass. The core, the innermost layer; it is composed of very dense elements, such as nickel and iron. What […]
