Considering the ideal gas law PV=nRT, what is P directly proportional to what variable?
1 Answer
Pressure is directly proportional to temperature and number of moles.
Explanation:
The ideal gas law equation looks like this
In order for two variables to have a direct relationship, they must increase or decrease at the same rate.
In other words, two variables are directly proportional if increasing one will cause the other to increase at the same rate. LIkewsie, decreasing one will cause the other to decrease at the same rate.
To see which variables are directly proportional to pressure, isolate
Since
So,
In other words, if
Likewise, if
On the other hand, if
As a conclusion,
