Question

In the figure displayed, what is the temperature and pressure of the critical point?Phase diagram. The x axis is labeled Temperature degrees Celsius, and increases by increments of 40, starting at negative 80 and ending at 760. The y axis is labeled Pressure (atm), and increases by increments of 1, beginning at 0 and ending at 15. There is a curved line that starts at -80, 0, which slopes gently upward and to the right, following an almost straight diagonal line until it reaches the point 600, 12, where it ends at a marked point. At the point where this line crosses 80, 2 another line starts that shoots upward almost vertically, but slightly off to the right. This line ends around the point 160, 15. The 2 lines previously mentioned divide the graph into 3 labeled sections. To the left of the almost vertical line, the graph is labeled solid. In between the line and the first mentioned curve, the graph is labeled liquid. To the right of the first mentioned curve, the graph is labeled gas. There is a dotted line that runs horizontally on y=7, from x=0 to x=760. On the far left this line is labeled A, and on the far right this line is labeled B.520°C and 7 atm80°C and 7 atm80°C and 2 atm600°C and 12 atm

Answer 1

600 °C and 12 atm

Step-by-step explanation

Consider the typical phase diagram and use the information gather from it and let us it to answer your question.

Comparing the critical point in the typical phase diagram above, we can conclude that the temperature and pressure of the critical point in the give phase diagram are 600 °C and 12 atm.

Thus, the correct answer is given in the last option: 600 °C and 12 atm.
