11.What is the difference between Ideal gases and Real gases?
-

Explanation:

They are the gases that conform to gas laws under all conditions of temperature and pressure. They are the gases that conform precisely to the assumptions of kinetic theory. ideal gases according to the kinetic theory assumptions could have no significant volume and there is no attractive or repulsive forces between its particles. there is no gas for which these assumptions are true; an ideal gas does not exist.  However, under many coditions of temperature and pressure real gases behave much like ideal gases. Real gases have volume and there are attractions between their particles. Because of these attractions, real gases can be solidified or condensed when compressed or cooled e.g. water vapor when cooled below 100 degrees celsius at standard atmospheric pressure  can be condensed into liquid. other real gases behave like that but sometimes more pressure and less temperature is required.

Assumptions of kinetic theory:

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
