Question

Argon is placed inside a container with a constant volume. The graph shows the estimated pressure $y$ , in $pounds per square inch (psi)$ , of the argon when its temperature is $x$ kelvins.

What is the estimated pressure of the argon, in $psi$ , when the temperature is $600$ kelvins?

Accepted Answer

Choice B is correct. For the graph shown, the x -axis represents temperature, in kelvins, and the y -axis represents the estimated pressure, in pounds &#160; per &#160; square &#160; inch &#160; psi . The estimated pressure of the argon when the temperature is 600 kelvins can be found by loing the point on the graph where the value of x is equal to 600 . The graph passes through the point 600 , 12 . This means that when the temperature is 600 kelvins, the estimated pressure is 12 &#160; psi . Choice A is incorrect. This is the estimated pressure, in psi , of the argon when the temperature is 300 kelvins, not 600 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.
