# Boiling & Critical Temperature: Understanding The Difference

• fxdung
In summary, boiling temperature and critical temperature are different things. The boiling temperature is dependent on pressure, while the critical point is a specific point with one pressure and temperature. For more information, please refer to the Wikipedia article on critical points in thermodynamics. Additionally, it is suggested to do further research in order to gain a better understanding of the topic before asking a question.

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

Different.

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...'

## What is boiling and critical temperature?

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.

## What is the difference between boiling and critical temperature?

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.

## Why is it important to understand the difference between boiling and critical temperature?

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.

## What factors affect the boiling and critical temperature of a substance?

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.

## Can boiling and critical temperature be used to identify a substance?

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.
