1. wat do we exactly mean by the "average momentum of a molecule" of an ideal gas??? 2. why does the avg momentum of a molecule of an ideal gas depend on volume, and not on pressure??? 3. The pressure of an ideal gas is written as p=(2E)/(3V) . Here E refers to "translational" K.E. My doubt here is : y does E refer ONLY to translational KE n NOT 'total" KE of the gas?? 4. While gas from a cookin gas cylinder is used, the pressure does not fall appreciably till the last few minutes. Why?? PLS PLS PLS explain n justify ur answers, esp. the last one....

The cylinder contains compressed gas in liquid form. So when the gas available in the gaseous state is used up, the compressed gas deliquifies and gets converted to gaseous form maintaining the pressure
