Answer:
the pressure of gas is 100.0 the volume is 500.0
Explanation:
It is a statement of fact. explains how energy is produced, and describes the behavior of energy.
A gas with a vapor density greater than that of air, would be most effectively displaced out off a vessel by ventilation.
The two following principles determine the type of ventilation: Considering the impact of the contaminant's vapour density and either positive or negative pressure is applied.
Consider a vertical tank that is filled with methane gas. Methane would leak out if we opened the top hatch since its vapour density is far lower than that of air. A second opening could be built at the bottom to greatly increase the process' efficiency.
A faster atmospheric turnover would follow from air being pulled in via the bottom while the methane was vented out the top. The rate of natural ventilation will increase with the difference in vapour density. Numerous gases that require ventilation are either present in fairly low concentrations or have vapor densities close to one.

Introduction
empirical formula
A table of values shows a list of the values for an independent variable, x, matched with the value of the dependent variable, y. In many cases, an equation can be used to relate the two values. If you know the equation, you can easily generate a table of values.
If you are given the table of values, you must determine how the two values are related and then write an equation that shows the relationship.
xy-2-1-100112When looking at the relationship between the y-values and the x-values, it's easy to see that each y-value is 1 more than the x-value. Therefore, the equation that describes this relationship is y = x + 1.
Develop a Rule When Given a Table of Values
Writing an Equation for a Table of Values
Look at the table below. There does not appear to be a constant rate of change.

In this example, we look at the ratio of the change in the pattern of y-values and x-values.




Even though there did not appear to be a constant rate of change, there is actually a constant rate of change of 2.
We're almost ready to write our equation.
We now know the value for m (the slope) in the equation y = mx + b is 2. Since m is 2, we know that each x-value is being multiplied by 2.
What else is happening to the x-value to get the corresponding y-value?
xProcessy-32(-3) + 3-3-12(-1) + 3132(3) + 3962(6) + 31572(7) + 317
We also need to add 3 to the product in order to get the corresponding y-value.
The equation that represents this table of data is y = 2x + 3.
