AmontonsGesetz
Amontons' law refers to one of two laws named after Guillaume Amontons that describe different physical phenomena. In thermodynamics, Amontons' law states that for a fixed amount of an ideal (or near-ideal) gas at constant volume, the pressure is directly proportional to the absolute temperature: P ∝ T. Equivalently, P1/T1 = P2/T2 when the volume and amount of gas remain unchanged. This relation underpins the linear relationship between pressure and temperature observed when heating a gas in a rigid container and is a precursor to the ideal gas law PV = nRT.
Historically, Amontons observed this proportionality through experiments heating air in sealed volumes in the late 17th
In practice, Amontons' law is often applied alongside the ideal gas law to estimate how temperature changes
There is also a separate Amontons' law of friction in tribology, which states that the frictional force
