==Key Stage 5==
===Meaning===
'''Charles' law''' states that for a fixed [[mass]] of an [[Ideal Gas|ideal gas]] at constant [[pressure]], its [[Volume (Space)|volume]] is [[Directly Proportional|directly proportional]] to its [[Absolute Temperature|absolute temperature]].

===About Charles' Law===
*'''Charles' Law''' is expressed mathematically as 𝑉∝𝑇.
*Demonstrates the relationship between volume and temperature of gases.
Assumes the [[gas]] behaves ideally and pressure remains constant.
Charles' law can be derived from the ideal [[gas]] law.
Important in understanding the behaviour of gases under different temperature conditions.
Used in various applications involving gases, such as ballooning and air conditioning.
Helps in predicting the expansion or contraction of gases with temperature changes.

===Formula===

<math>T\propto V</math>

<math>\frac{V}{T}=constant</math>

Where,

V is the [[Volume (Space)|volume]] of the [[Ideal Gas|ideal gas]],

and

T is the [[temperature]] of the [[Ideal Gas|ideal gas]]

When there is a change of [[temperature]] and [[Volume (Space)|volume]] of a known amount of an [[Ideal Gas|ideal gas]] at constant [[pressure]] the following formula can be used:

<math>\frac{V_1}{T_1}=\frac{V_2}{T_2}</math>

Where the number represents before and after the change.

===Examples===

A balloon expands when heated due to the increase in volume as per Charles' law.
Hot air balloons rise because the heated air inside expands, making it less dense than the surrounding air.
