Score Sinus Tachycardia during sleep for a sustained sinus heart rate of greater than ___ beats per minute for adults.

We learned in Experiment 08 that the molecular weight of the Heavy species is 7 times greater than the molecular weight of the Light species.  In the current experiment, at a given temperature with the same number of molecules, we found that their pressures were about the same.  How is it possible for the Light species to exert the same pressure as the Heavy species? 

Cyclic changes in the heart rate during breathing. It is very common in children and often found in young adults.

PR interval normal, ___ seconds.

In Part II of this experiment, “Free Expansion”, a 5 nm wide box containing 200 heavy molecules is quickly expanded to 15 nm wide.  I observed this process to be:
