Charles’s law, an essential principle in gas behavior, describes the direct relationship between the volume and temperature of a gas at constant pressure. As the temperature of a gas increases, its volume expands proportionally, while a decrease in temperature leads to a decrease in volume. This relationship holds true for any quantity of gas, making these four entities—temperature, volume, constant pressure, and gas quantity—key aspects of Charles’s law.
Charles’ Law and What Stays Constant
Charles’ Law explores how the volume of a gas changes in relation to its temperature under constant pressure. Understanding which variable remains constant in this equation is crucial for comprehending the principles behind this law.
Charles’ Law Formula: V/T = constant
Breakdown of the Formula:
- V represents the volume of the gas
- T represents the temperature of the gas in Kelvin
What Stays Constant?
According to Charles’ Law, the ratio of the volume (V) of a gas to its temperature (T) remains constant when the pressure is held constant. This means that as the temperature of the gas increases, the volume of the gas also increases. Conversely, when the temperature decreases, the volume of the gas decreases.
Visual Representation:
The relationship between volume and temperature at constant pressure can be illustrated graphically:

Table of Constant Variables:
| Variable | Constant or Variable |
|---|---|
| Temperature (T) | Constant |
| Pressure (P) | Constant |
| Volume (V) | Variable |
Real-World Application:
Imagine a balloon filled with air at room temperature. If the balloon is heated, the air inside will expand, causing the balloon to expand as well. This is because the temperature (T) has increased, causing the volume (V) to increase while the pressure (P) remains constant.
Question 1:
What aspect of the gas sample remains unchanged when its temperature varies according to Charles’s Law?
Answer:
The volume of the gas sample stays constant when its temperature varies, as stated by Charles’s Law.
Question 2:
Under Charles’s Law, which variable maintains a constant value while the gas volume changes?
Answer:
Temperature remains constant while the gas volume changes according to Charles’s Law.
Question 3:
What is the invariant quantity in Charles’s Law that relates temperature and volume?
Answer:
The ratio of temperature to volume is a constant value in Charles’s Law.
