What does the point at which your curve crosses the horizontal axis represent?

• Chemistry -

What type of curve? As in what are you graphing..? It's impossible to tell without that bit of info! :)

I am graphing temperature vs volume. Temperature-horizontal axis, Volume-vertical axis.

• Chemistry -

Still difficult to decide on the experiment. Perhaps you could give a little more detail. Is the horizontal temp axis at zero volume?

• Chemistry -

so we did a chemistry lab to find the relationship between temperature and volume or charle's law. In the experiment, i got t1v1=372K, 267.2 cm^3
t2v2=277K,169.1 cm^3
so i graphed that
THen they told us to chose 2 other points from that line, TaVa and TbVb and find its K value.
i chose TaVa=200, 70
TbVb=240,110
then k value of TaVa=0.35
K value of TbVb=0.46
Then they asked what does the point at which your curve crosses the horizontal axis represent?
