Charles 's Law of temperature and volume helped discover the concept of absolute zero. Charles discovered that when a fixed amount of gas is cooled at constant pressure, the volume of the gas decreases. When looking at a graphical representation of Charles’s Law the temperature in which the volume is said to be zero is -273.15 degrees Celsius, in which it is now referred to as absolute zero.
Charles’s Law describes that temperature and volume are directly proportional. Therefore, when temperature increases, volume increases and the same for the opposite, when the temperature decreases, the volume decreases as well. The mathematical way to display Charles’s Law is where the V represents the volume of the gas, the T represents the temperature of the gas , and b represents the pressure of the gas.
The graphical representation of Charles’s law is shown as a graph where the x-axis is the temperature in degrees Celsius and the y-axis represents the volume of gas in milliliters. The relationship between temperature and volume creates a positive slope in the graph itself, in which it demonstrates that when the temperature increases the volume of gas increases as well.
As the graph continues to represent the relationship of volume and temperature of the gas, when the temperature decreases to a point where the temperature is zero degrees Celsius, the volume is not zero. As the gas is cooled beyond zero degrees Celsius, as it is shown by the graphical representation in the…
