Charles’s law states that the volume of an ideal gas. is directly proportional to the. absolute temperature at constant pressure. The law also states that. the Kelvin temperature and the volume. will be in direct proportion. when the pressure exerted on a sample of a dry gas is held constant. Charles’s Law. also sometimes referred to as the law of volumes. gives a detailed account of how gas expands when the temperature is increased. Conversel, when there is a decrease in temperature. it will lead to a decrease in volume. When we compare a substance. under two different conditions. from the above statement we can write this in the following manner. As absolute temperature increases. the volume of the gas also goes up in proportion. In other words. Charles’s law is a special case of the ideal gas law. The law is applicable to the ideal gases. that are held at constant pressure. but the temperature and volume keep changing. Charles’s Law formula is written as. VI /TI=VF /TF Where VI=Initial volume VF=Final volume TI=Intial absolute temperature TF=Final absolute temperature Here. we should remember that. the temperatures are absolute temperatures. that are measured in Kelvin. not in Fahrenheit or Celcius. In cold weather or in a cold environment. helium balloons shrink. In winters when the weather is cool. the capacity of the human lung decreases. This makes it more difficult for the athletes to perform on a freezing winter day. and it also makes it difficult for people to go jogging. In winters as the temperature decreases. when you take a basketball outside. in the ground the ball shrinks. This is the only reason. why it is important to check the pressure in the car tyres. when you go outside in the cold days. This is also the case with. any inflated object and explains why. it’s a good idea to check the pressure in your car tyres. when the temperature drops.
