Kinetic energy of gas - Study guides, Class notes & Summaries

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...

Pneumatic Exam Questions and Answers Already Passed The amount of force required to lift, move, or alter the speed or direction of an object is determined by its inertia. True Pressure gauges in pneumatic systems typically measure pressures above atmospheric pressure. True In a pneumatic system, the motor generates mechanical energy. False Pascal's Law indicates that when a gas is under pressure in a closed container, this pressure is distributed evenly in all directions by th...

Kinetic molecular theory ANSWER: • Gases are all hard spheres • They are small relative to size of system volume • They undergo elastic collisions and don't stick or react• They have a T equal system T that gives all of them the sameEk • They all have the same Ek, butEk=½ mv2so they have different velocity as inverse square of mass m1v1^2= m2v2^2 also applies to diffusion and effusion m1d1^2= m2d2^2 •Velocities in vacuum >> than velocities when diffusing through ga...
