H. less, because there were fewer N 2 molecules per gram than there were NO 2 molecules per gram.
J. less, because there were more N 2 molecules per gram than there were NO 2 molecules per gram.
- Suppose the experiment involving N 2 and the 4 L vessel had been repeated, except at a temperature of 287 K. For a given mass of N 2 ,
compared to the pressure measured in the original experiment, the pressure measured at 287 K would have been:
A. greater, because pressure is directly proportional to temperature.
B. greater, because pressure is inversely proportional to temperature.
C. less, because pressure is directly proportional to temperature.
D. less, because pressure is inversely proportional to temperature.
