Explain the cause of Brownian motion
Briefly define or explain the cause of Brownian motion?
Expert
Molecules in the gas move constantly, freely, arbitrarily, in all the directions and at high speeds. They are capable to do so as the intermolecular force of attraction among the molecules is negligible whenever in a gaseous state. This constant motion of molecules causes them to collide with everything in their path. For illustration, the dust particles will be bombarded through the molecules moving at high speeds, causing them to encompass a zigzag motion.
Brownian motion as well occurs in molecules in a liquid, however to a less obvious extent than in the gas.
Brackett series (Brackett) - The series (or sequence) that explains the emission spectrum of hydrogen whenever the electron is jumping to fourth orbital. All of the lines are in the infrared segment of the spectrum.
Name the instrument which is used to measure the volume? Explain in short?
Briefly describe the applications of the nmr spectroscopy?
Bell's inequality (J.S. Bell; 1964) - The quantum mechanical theorem that explains that if the quantum mechanics were to rely on the hidden variables, it should have non-local properties.
Pfund series: The series that explains the emission spectrum of hydrogen whenever the electron is jumping to the fifth orbital. Each line is in the infrared part of the spectrum.
Describe why is heavy water employed as a moderator? Illustrate.
Pascal: Pa The derived SI unit of pressure stated as 1 N acting over a region of 1 m2; it therefore has units of N/m2
Briefly describe the reason why it takes longer to heat a bucket of water than the cup of water?
Metre: meter; m: The basic SI unit of length, stated as the length of the path traveled by light in vacuum throughout a period of 1/299 792 458 s.
Kohlrausch's law (F. Kohlrausch): When a salt is dissolved in water, the conductivity of the solution is the addition of two values -- one depending on the positive ions and the other on negative ions.
