Question

Hydrogen is placed inside a container and kept at a constant pressure. The graph shows the estimated volume $y$ , in liters, of the hydrogen when its temperature is $x$ kelvins.

What is the estimated volume, in liters, of the hydrogen when its temperature is $500$ kelvins?

Accepted Answer

Choice C is correct. For the graph shown, the x -axis represents temperature, in kelvins, and the y -axis represents volume, in liters. Therefore, the estimated volume, in liters, of the hydrogen when its temperature is 500 kelvins is represented by the y -coordinate of the point on the graph that has an x -coordinate of 500 . The point on the graph with an x -coordinate of 500 has a y -coordinate of 7 . Therefore, the estimated volume, in liters, of the hydrogen when its temperature is 500 kelvins is 7 . Choice A is incorrect and may result from conceptual errors. Choice B is incorrect and may result from conceptual errors. Choice D is incorrect and may result from conceptual errors.
