A postulate of the kinetic molecular theory is listed. Postulate: Gas particles are in constant random motion.

Which of the following activities can be used to demonstrate the postulate?
Recording the change in pressure when heating an inflated tire
Observing the change in an inflated balloon when placed in cold liquefied nitrogen
Observing the ease of pushing the plunger of a blocked nozzle syringe containing gas
Recording the speed of colored gas spreading from one jar to an empty jar

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
