what is Charles law explain
Answers
Charles 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.
What is Charles Law?
Charles’ Law, also sometimes referred to as the law of volumes, gives a detailed account of how gas expands when the temperature is increased. Conversely, 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:
V2/V1=T2/T1
OR
V1T2=V2T1
This above equation depicts that as absolute temperature increases, the volume of the gas also goes up in proportion.
In other words, Charle’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 Law Formula
Charle’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 ⁰F or ⁰C.
Answer:
Kepler's first law the orbit of a planet is an ellipse with the sun at one of the foci.
Kepler's second law on the line joining the planet and the sun sweeps equal areas in equal interval of time
Kepler's third law the square of its period of revolution around the sun is directly proportional to the cube of the mean distance of a planet from the sun
