Charles's Law
The Relationship Between Temperature and Volume in Gases
Charles's Law is a fundamental principle in thermodynamics that explains the direct relationship between the temperature and volume of a gas when pressure remains constant.
The volume of a gas is directly proportional to its temperature, provided the pressure remains constant. In simple terms, as the temperature of a gas increases, its volume also increases, and vice versa.
This relationship is captured in the formula:
\(\frac{V_1}{T_1} = \frac{V_2}{T_2}\)
Where:
Two key details to keep in mind when it comes to Charles's Law.
Always convert temperatures to Kelvin
(\(K = °C + 273\)) to accurately apply Charles's Law.
The law only applies if the pressure remains unchanged.
