What is Critical Temperature?
Critical temperature is the temperature at which the vapor pressure of a substance equals the atmospheric pressure.
What happens When We Heat above the Critical Temperature?
When we heat an element above the critical temperature, the atoms in the element become so excited that they break free of the solid and enter into a gas. The element then becomes a plasma.
Graphical Representation of Critical Temperature
The graphical representation of the critical temperature of a substance is a graph that shows the temperature at which the substance changes from a liquid to a gas. The y-axis of the graph represents the temperature, and the x-axis represents the pressure. The points on the graph represent the critical temperature of different substances.
Example (Critical Temperature and Critical Pressure):
The critical temperature and critical pressure of a substance is the temperature and pressure at which the substance undergoes a phase change from a liquid to a gas. The critical temperature is the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure. The critical pressure is the pressure at which the liquid and gas are in equilibrium.
