Are boiling temperature and critical temperature the same or they are different things?

The one-word answer you got to this question is a prompt that you should google it/read the wiki article on it. That would either answer the question without the need to ask it here or focus the question and show you've put some effort into it; 'I know the definition of "critical point" is...but I don't understand how that's different from...'fxdung said:Are boiling temperature and critical temperature the same or they are different things?
Boiling temperature is the temperature at which a liquid changes into a gas. Critical temperature is the temperature at which a gas cannot be turned into a liquid, no matter how much pressure is applied.
The main difference between boiling and critical temperature is that boiling temperature is dependent on pressure, while critical temperature is not. Boiling temperature can change with pressure, but critical temperature remains constant.
It is important to understand the difference between boiling and critical temperature because it affects the behavior of substances under different conditions. For example, substances with a low critical temperature cannot be liquefied at room temperature, making them unsuitable for use as refrigerants.
The boiling and critical temperature of a substance are affected by its molecular structure, intermolecular forces, and the amount of pressure applied. Substances with stronger intermolecular forces will have higher boiling and critical temperatures.
Yes, boiling and critical temperature can be used to identify a substance. Each substance has a unique boiling and critical temperature, which can be used as a characteristic property to identify it. This is often used in chemistry and forensics to determine the composition of unknown substances.
