Write an equation for the combined gas law, using temperature in degrees celsius. explain why the kelvin scale is convenient.

The combined gas law

There are several gas equations in various processes:  

In the same temperature and pressure, in the same volume conditions, the gas contains the same number of molecules  

So it applies: the ratio of gas volume will be equal to the ratio of gas moles

At a fixed temperature, the gas volume is inversely proportional to the pressure applied  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature  

Combined with Boyle's law and Gay Lussac's law  

P1 = initial gas pressure (N / m2 or Pa)  

V1 = initial gas volume (m3)  

P2 = gas end pressure  

V2 = the final volume of gas  

T1 = initial gas temperature (K)  

T2 = gas end temperature  

Can be concluded

Boyle's law at constant T, P = 1 / V ⇒PV = k

Charles's law, at constant P, V = T ⇒V/T = k

Gay Lussac's Law , constant V, P=T⇒P/T = k

Avogadro's law, at constant P and T, V = n  

So an equation for the combined gas law :

Become the general ideal gas equation  

PV = nRT  

PV = NkT  

N = number of gas particles  

n = number of moles  

R = gas constant (8,31.10³ J / kmole K  

k = Boltzmann constant (1,38.10⁻²³)  

n = = N / No  

n = m / M  

n = mole  

No = Avogadro number (6.02.10²³)  

m = mass  

M = relative molecular mass  

Absolute zero point of the Kelvin scale can better indicate the condition of a substance that has frozen, so the Kelvin scale is always positive and easy to calculate
