Molecular motion - Study guides, Class notes & Summaries

What is the Kinetic Theory of gases correct answersGases are composed of discrete molecules 1.Molecules are in random motion 2.Molecular collisions are elastic 3.Molecular activity depends on temp. 4.No physical attraction b/t molecules describe the Bernoulli Principle correct answers1. gas flow through a tube 2. As velocity of gas goes up, lateral pressure goes down since the total energy principle is constant. What is the relationship between temperature & pressure? correct answersA...

Astronomy Science Olympiad Master Latest Update Graded A+ Optical double not actually binaries simply two stars lying along same line of sight (similar RA & dec) Not gravitationally bound Not usefull in determining stellar masses Visual binary both stars resolved independently if orbital pd not too long, can monitor motion provides angular separation from center of mass If dist known, linear separations can be calculated Astrometric binary If one significantly brighter, not pos...

Both A and B are correct All of the above are correct --*correct answer*--Both A and B are correct In simple diffusion a solute Is propelled by random molecular motion Moves up its concentration gradient Moves across a membrane because of an input of free energy. Both A and B are correct All of the above are ...

Chapter 1 Carbon and Its Compounds CHECKPOINT PROBLEMS Practice Problem 1.1 a) S — 1s2 2s2 2p6 3s2 3p4 b) Cl — 1s2 2s2 2p6 3s2 3p5 c) Na+ — 1s2 2s2 2p6 1-2 Copyright © 2018 Nelson Education Limited Practice Problem 1.2 a) Count valence electrons. Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence electrons. Build a bas...

Conduction - Answer-direct transfer of energy from molecule to molecule via direct molecular collsions What are the best and worst conductors? - Answer-Worst= gases Best= metals Convection - Answer-heat transfer by physical motion; only takes place in fluids and gases. Heat energy is transferred AWAY from the source. Radiation - Answer-transfer of energy by electromagnetic waves. Radiation can travel through a hard vacuum. Ex: energy from sun specific heat - Answer-c, amount of he...

MODULE 3 LECTURE 1: Define diffusion Which 4 factors does it depend on? What are the 2 components of random motion? - correct answer diffusion: random/non-directed motion of molecules and small particles in a liquid factors: 1) driving force (i.e. gradient, temp.) 2) mechanical resistance of the surrounding medium 3) structural properties of the molecule 4) active forces causing non-thermal fluctuations (i.e. contraction/relaxation o...
