Question

Oxygen gas is placed inside a tank with a constant volume. The graph shows the estimated temperature $y$ , in kelvins, of the oxygen gas when its pressure is $x$ atmospheres.

What is the estimated temperature, in kelvins, of the oxygen gas when its pressure is $6$ atmospheres?

Accepted Answer

Choice C is correct. For the graph shown, the x -axis represents pressure, in atmospheres, and the y -axis represents temperature, in kelvins. Therefore, the estimated temperature, in kelvins, of the oxygen gas when its pressure is 6 atmospheres is represented by the y -coordinate of the point on the graph that has an x -coordinate of 6 . The point on the graph with an x -coordinate of 6 has a y -coordinate of approximately 700 . Therefore, the estimated temperature, in kelvins, of the oxygen gas when its pressure is 6 atmospheres is 700 . Choice A is incorrect. This is the pressure, in atmospheres, not the estimated temperature, in kelvins, of the oxygen gas when its pressure is 6 atmospheres. Choice B is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
