Answer explanation
Choice B is correct. For the graph shown, the x-axis represents temperature, in kelvins, and the y-axis represents the estimated pressure, in . The estimated pressure of the argon when the temperature is kelvins can be found by loing the point on the graph where the value of is equal to . The graph passes through the point . This means that when the temperature is kelvins, the estimated pressure is .
Choice A is incorrect. This is the estimated pressure, in , of the argon when the temperature is kelvins, not kelvins.
Choice C is incorrect and may result from conceptual or calculation errors.
Choice D is incorrect. This is the temperature, in kelvins, of the argon.
