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....
