This experiment deals with the relationship between volume and temperature for a fixed amount of gas at constant pressure. design an experiment, which would allow you to study the relationship between pressure and temperature for a fixed amount of gas at constant volume. show a diagram of the apparatus and a plot of p versus t for the data you expect to obtain. is the relationship between p and t direct or inverse?

Your experiment should keep one thing constant and measure the other. So vary the temp and measure the pressure. You will get a set of data that relates pressure with temp.
PV = nRT
So
P and T are directly proportional.
These experiments are one of either Boyle-Mariottte's, Gay-Lussac'a or Charles' law.

reserve is the answer

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
