A region of the galaxy where new stars are forming-contains a very tenuous gas with 100 #a t oms ##/cm^3#. This gas is heated to #7500 K# by ultraviolet radiation from nearby stars. What is the Gas Pressure in ATM?
The pressure of the gas under these conditions would be
At this extremely low pressure, the ideal gas law gives an accurate estimate.
First, we must convert
Since there are
Next, since there are
In the ideal gas law, the above value would represent
we need only multiply the above value by
The result is in atmospheres of pressure due to the choice made for the value of
