Behavior of Gases Review
True or False: One mole of any gas, regardless of size, temperature, or pressure occupies 22.4L? 1. True 2. False 0% 0% True False
True or False: STP is at 0 Kelvin and 760mmHg. 1. True 2. False 0% 0% True False
Which of the following is not a main idea of the kinetic molecular theory of gases? 1. The average kinetic energy of gas particles is proportional to the Kelvin temperature. 2. Gases consist of molecules moving at extremely high velocities. 3. STP is at 0oC and 1atm. 4. The volume of the individual gas molecules is huge compared to the volume that the gas occupies. 0% 0% 0% 0% STP is at 0o C... Gases consist ... The volume of ... The average ki...
If the total atmospheric pressure is 760mmHg, then all of the components of the air (nitrogen, oxygen, ) have a pressure of 760mmHg. 1. True 2. False 0% 0% True False
Why is a gas easier to compress than a liquid or a solid? 1. Its volume increases more under pressure than an equal volume of liquid does. Its volume increases more under pressure than an equal volume of solid does. The space between gas particles is much less than the space between liquid or solid particles. The volume of a gas s particles is small compared to the overall volume of the gas. 2. 3. 4. 0% 0% 0% 0% Its volume increases mo.. The space between gas p... Its volume increases mor...
