Charles' Law

Charles' Law:
Tells us that temperature and volume vary directly with each other. This holds true at constant pressure. As temperature increases = volume increases.

Temperature must be in Kelvin which is 273.15 K. So degree C + 273.15 = _______

As the temperature of a gas increases, it gains energy. This will result in an increase in contacting the sides of their containers -- they are going to want to expand. Keep in mind, Charles Law holds true at constant pressure. If the pressure is going to stay the same, the system has no choice but to allow for the gas to expand --resulting in an increase in the volume of the gas.

If Charles Law is extrapolated backwards, where volume = 0, the value of absolute 0 can be achieved. We call this -273.15 degrees Celsius (Kelvin can't be negative!!!!), absolute zero. There is no kinetic movement of molecules at all.
