the ideal gas equation is given by PV=nRT. sketch the following
graphs for an ideal gas. show all working steps for the derivation
of the graph.
a) P against n at constant V and T
b) PV against (1/V) at constant n and T(degree celsius)
c)P against T(degree celsius) at constant V and n.
d) density/P against P at constant T.
so far, for (a), i got a straight line graph through the origin.
for (c), i got a straight line graph through a point on the
y-axis.( do i have to state the gradient on the graph? for eg,
for a) gradient=(RT/V)? )
for (d) , i got a horizontal graph with (M/RT) being the point
on the y-axis.
is my answers correct for all of these? i cant figure out how to
do (b)..
Your answers are correct.
You do not need to specify gradient unless the question requires
it.
For PV against (1/V) at constant n and T, it is a horizontal
straight line, somewhere above the x-axis.
Note that the correct nomenclature (ie. what your teacher should
use when setting questions) uses T for Kelvins and t for deg
C.
