Mine Combined-Charles' Law and Boyle's Law Quiz w/Practice Problems, Gas Laws exam Already Passed!!

When pressure increases, volume - decreases When temperature increases, volume - increases Boyle's Law - When the temperature and moles are constant, the pressure and volume are inversely proportional Charles' Law - When the pressure and moles are constant, the temperature, and volume are directly proportional A sample of oxygen gas occupies a volume of 250 mL at 740 torr pressure. What volume will it occupy at 800 torr pressure? - ((740 torr)(250 mL))/800 torr 231 mL A sample of carbon dioxide occupies a volume of 3.50 liters at 125 kPa pressure. What pressure would the gas exert if the volume was decreased to 2.00 liters? - ((125 kPa)(3.50 L))/2.00 L 219 kPa A sample of nitrogen occupies a volume of 250 mL at 25 C. What volume will it occupy at 95 C? - ((250 mL)(368 K))/298 K 309 mL Oxygen gas is at a temperature of 40 C when it occupies a volume of 2.30 Liters. To what temperature should it be raised to occupy a volume of 6.50 Liters? - ((6.50 L)(313 K))/2.30 L 885 KBoyle's Law - Inverse Charles Law - Direct Gay-Lussac's Law - Direct Boyle's Law - For a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure decreases. Charles Law - For a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature increases. Gay-Lussac's Law - For a fixed amount of gas at a constant volume, the pressure of the gas increases as the temperature increases. Temperature - the average kinetic energy of gas particles. (i.e. how fast the particles move); ALWAYS USE KELVIN
