Consider the phase diagram for carbon dioxide. In what phase is CO2 at 4 atm and -10 \u00c2\u00b0C? – Solid – Liquid – Gas Starting from the same point; 1 atm and 0 \u00c2\u00b0C, what phase change would eventually result from an increase in pressure? – Condensation – Vaporization – Melting – Deposition – Sublimation<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Here are the step-by-step solutions to the questions based on the provided phase diagram for carbon dioxide.<\/p>\n\n\n\n

Question 1: In what phase is CO\u2082 at 4 atm and -10 \u00b0C?<\/strong><\/p>\n\n\n\n

    \n
  1. Locate the point:<\/strong>\u00a0Find the temperature -10 \u00b0C on the horizontal axis (Temperature). This is to the right of -56.4 \u00b0C.<\/li>\n\n\n\n
  2. Find the pressure:<\/strong>\u00a0Locate the pressure 4 atm on the vertical axis (Pressure). This is between the marked points 1.0 atm and 5.11 atm.<\/li>\n\n\n\n
  3. Identify the phase:<\/strong>\u00a0Trace a vertical line up from -10 \u00b0C and a horizontal line across from 4 atm. The point where they intersect falls within the region labeled\u00a0gas<\/strong>.<\/li>\n<\/ol>\n\n\n\n

    Answer:<\/strong> The correct option is gas<\/strong>.<\/p>\n\n\n\n

    \n\n\n\n

    Question 2: Starting from the same point, 4 atm and -10 \u00b0C, what phase change would eventually result from an increase in pressure?<\/strong><\/p>\n\n\n\n

      \n
    1. Identify the starting point:<\/strong>\u00a0As determined above, the point (4 atm, -10 \u00b0C) is in the\u00a0gas<\/strong>\u00a0phase.<\/li>\n\n\n\n
    2. Understand the change:<\/strong>\u00a0“An increase in pressure” at a constant temperature means moving straight up vertically on the diagram from your starting point.<\/li>\n\n\n\n
    3. Observe the transition:<\/strong>\u00a0As you move vertically up from the point (4 atm, -10 \u00b0C), you will cross the boundary line separating the\u00a0gas<\/strong>\u00a0phase from the\u00a0liquid<\/strong>\u00a0phase.<\/li>\n\n\n\n
    4. Name the phase change:<\/strong>\u00a0The transition from a gas to a liquid is called\u00a0condensation<\/strong>.<\/li>\n<\/ol>\n\n\n\n

      Answer:<\/strong>\u00a0The correct option is\u00a0condensation<\/strong><\/p>\n\n\n\n
