Document Summary
R+mn 9. 1 p # 1-4 q # 5. Motion increases and spaces increase as temp increases. Very cold all atoms behave in unison as a single large atom! Very hot electrons separated from nuclei electron/nucleus soup. Inv 9. 2. 1 or overhead apparatus or handout. Barometer measures atmospheric pressure (pressure of air above you) an altimeter is just a barometer! For weather what do you watch for with the barometer. Pressure the amount of force per unit area. Units pa where 1 pa = 1 n m2 get a 100g mass as an example of 1 n that"s very small so the unit kpa is used instead. Atmospheric pressure is approximately 100 kpa or 760 mm. In imperial units pressure is measured in psi (pounds per square inch) and atmospheric pressure is 14. 7 psi. Blood pressure - (120 over 80 torr above atmospheric pressure. Proved hg in barometer was measuring air pressure. Developed a relationship between p and v using j-shaped tube.
