Question

Refer to figure 1(above) and Chap 3 power point to answer the questions below:

1. State the temperature and pressure of triple point of carbon dioxide:

Temperature: ____°C

Pressure: _____Kpa

The image presents a phase diagram illustrating the states of matter (solid, liquid, gas) and supercritical fluid (SCF) in relation to pressure and temperature.

- **Axes:**
  - The vertical axis represents Pressure (kPa), ranging from 10 to 1,000,000 kPa on a logarithmic scale.
  - The horizontal axis depicts Temperature (°C), ranging from -100 to 100°C.

- **Regions:**
  - **Solid Region:** Shaded in blue, located at lower temperatures and higher pressures.
  - **Liquid Region:** Shaded in purple, occupying intermediate temperatures and pressures.
  - **Gas Region:** Shaded in orange, at higher temperatures and lower pressures.
  - **Supercritical Fluid (SCF):** Shaded in green, occurring at high temperatures and pressures, beyond the critical point (T_C).

- **Curves:**
  - The boundary curves delineate transitions between the phases of matter (e.g., melting, boiling) and the supercritical state.

This diagram is crucial for understanding the conditions under which a substance exists in different states and transitions between them.

Expert Solution
Step 1

The triple point is the point of interception at which the substance has fixed pressure and temperature. This is also the point at which three phases namely solid, liquid and gas coexist in equilibrium.
