Term
What is the mean kinetic energy for each molecule tpe in an ideal gas mixture having a pressure of P, gas constant R, and a density of rho? |
|
Definition
For each molecule type the temperature is the same and T=(1/3K)mV^2 = 3kt/2=3kp/2rhoR |

|
|
Term
Speeds or the velocity components are inversely proportional to the mass of the molecule. explain |
|
Definition
ideal gas have elastic collision so lessinertial will over experience higher speeds due to collisions with the more massive molecules having greater inertia. conservation of momentum and ke. newtons third law. the less massive molecules have lower inertia their direction and speed changes will be altered more considerably. |
