What is critical point?

Text Solution

### Step-by-Step Text Solution: 1. **Understanding the Critical Point**: The critical point is a specific condition of temperature and pressure at which the properties of a gas and a liquid become indistinguishable. At this point, the phase transition between liquid and gas ceases to exist. 2. **Graphical Representation**: To visualize the critical point, we can refer to a graph where the y-axis represents pressure and the x-axis represents temperature. The critical point is located at the end of the liquid-gas phase boundary line on this graph. 3. **Equilibrium of Phases**: At the critical point, the liquid and gas phases are in equilibrium. This means that the transition between liquid and gas occurs without any distinct phase change. ...
