Differbetween
1 Answer. The combined gas law relates the variables pressure, temperature, and volume whereas the ideal gas law relates these three including the number of moles. k is a constant. Where P,V,T represent the same variables as in the combined gas law.

What is the combined gas law used for?
The combined gas law expresses the relationship between the pressure, volume, and absolute temperature of a fixed amount of gas. For a combined gas law problem, only the amount of gas is held constant.
What is the ideal gas law a combination of?
The combined gas law combines the three gas laws: Boyle's Law, Charles' Law, and Gay-Lussac's Law. It states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant. When Avogadro's law is added to the combined gas law, the ideal gas law results.
What is an example of the combined gas law?
For a given quantity of gas, it has been found experimentally that the volume of the gas is inversely proportional to the pressure applied to the gas when the temperature is kept constant. That is, V∝1P at a constant T. For example, if the pressure on a gas is doubled, the volume is reduced to half its original volume.
What is the difference between ideal gas and perfect gas?
An ideal gas is the same as a perfect gas. Just different naming. The usual name for such gases (for which is assumed that the particles that make up the gas have no interaction with each other) is ideal gas, perfect gas is what such a gas is named in Atkins physical chemistry book.
Does combined gas law have to be in liters?
Units first! Volume in liters, milliliters, or cm 3 Temperature must always be in KELVIN!!! Pressure can be in atmospheres, torr, or.
Who discovered the ideal gas law?
The ideal gas law was discovered by physicist and engineer Benoît Paul Émile Clapeyron (seen on the right) in 1834. You may have seen the equation PV = nRT in your classes before.
What units are used in PV nRT?
In SI units, p is measured in pascals, V is measured in cubic metres, n is measured in moles, and T in kelvins (the Kelvin scale is a shifted Celsius scale, where 0.00 K = −273.15 °C, the lowest possible temperature).
What is ideal gas equation derive it?
The most common form of this equation is since PV= K and V/T =k then. PV/T = constant. Thus, the Ideal Gas Equation is given as. PV = nRT. where P= pressure of the gas; V=volume of the gas; n= Number of Moles; T=Absolute temperature; R=Ideal Gas constant also known as Boltzmann Constant = 0.082057 L atm K-1 mol-1.
Do units matter combined gas law?
The constant, k, will also depend on the number of moles and could therefore vary. Any units will work here for pressure and volume but the temperature must be absolute (Kelvin). ...
