theory is that gas particles are always in motion‚ like the other states of matter. But they are different in that they undergo random translational movement. In solids‚ the particles mainly experience vibrational motion and in liquids they mainly vibrate and rotate‚ with some translational motion. Gas particles move rapidly in straight lines‚ unless acted upon by another particle or the walls of a container. This continuous contact with the container leads to our understanding of gas pressure‚ the

3: Problems & Answers Week 4: Feb 2- 6‚ 2009 1. Consider a gas that occupies 1.00 dm3 at a pressure of 2.00 bar. If the gas is compressed isothermally at constant external pressure‚ Pext‚ so that the final volume is 0.500 dm3‚ what is the smallest value Pext can have? Calculate the work involved using this value of Pext. Solution For compression to occur‚ the value of Pext must be at least as large as the final pressure of the gas. P1 = 2.00 bar‚ V1 = 1.00 dm3‚ V2 = 0.500 dm3‚ P2 = ? = 4
