Question



uestions On the basis of the graphs you have plotted and the equation you learned, what is the relationship between the volume of a gas and the pressure that is exerted on it? result Explain your 2. Calculate the gas constant R from the slope of the second graph. For this calculation, you need to measure the room temperature T in Kelvin and calculate the number of moles (n) of the air inside the injector. Remember the initial volume of the air in the syringe, the pressure, and the ambient temperature. To calculate the gas constant, use the following fact: the standard state (100kPa, 293K, 24.7L) contains I mole of gas. Thus, if you had 30 cm at 100 kPa, you can estimate the number of moles: 30/1000 22.7 n= Notice that we did not consider the temperature factor. So, this is an approximation. Compare your result with the known value R = 8.31[J / K-mol]

Explanation / Answer

1)

The slope of the graph is negative. This means that as one parameter is increased, the other parameter decreases.

This shows that the pressure P and the volume V are inversely proportional.

That is,

V -> 1/P

Or in the other way,

P -> 1/V
