Question

For an ideal gas, predict the shape of the plot for each of these graphs where P is pressure, V is volume, and T is absolute volume.? I attached a picture and selected the answers to this question, please tell me if I am wrong or correct, and what the answers should be. Thank you.

Answer 1

For a pressure vs 1/volume graph, the pressure is proportional to 1/volume so it won't be a straight line.

For a pressure volume graph it would be the opposite like a exponential function that starts off at a high value when the pressure is low on the x axis and then gets smaller as you increase x this case volume.

For volume and temperature those two values will be proportional to one another hence a straight line.

Do you understand why these relationships are like this?
