Charles's Law

Charles's Law states that the volume of a gas is directly proportional to its temperature, given that pressure and amount of gas remain constant. In other words, as the temperature of a gas increases, the volume of the gas also increases, and vice versa.

Mathematical Representation

The mathematical representation of Charles's Law is:

V1 / T1 = V2 / T2

Where: V1 = initial volume of the gas T1 = initial temperature of the gas (in Kelvin) V2 = final volume of the gas T2 = final temperature of the gas (in Kelvin)

Application and Practical Examples

Charles's Law is often observed in everyday situations. For example, when a balloon is heated, the air inside the balloon expands, causing the balloon to inflate. This is because the increase in temperature leads to an increase in the volume of the gas inside the balloon, in accordance with Charles's Law.
