What is the combined gas law used for?
Applications. The combined gas law has practical applications when dealing with gases at ordinary temperatures and pressures. Like other gas laws based on ideal behavior, it becomes less accurate at high temperatures and pressures. The law is used in thermodynamics and fluid mechanics.6 мая 2019 г.
What is the difference between ideal gas law and combined gas law?
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.17 мая 2014 г.
Who made the combined gas law?
The pressure-temperature law was discovered by Jacques Charles and Joseph Gay-Lussac (1778-1850), a French scientist. It was not given a name because it is easily obtained by using Boyle’s and Charles’ Laws properly, however, it is given below for your enjoyment.
What is the combined gas law quizlet?
Combined Gas Law. Expresses the relationship between pressure, volume, and temperature of a fixed amount of gas. Ideal Gas Law. States the math relationship of pressure (P), volume (V), temperature (T), the gas constant (R), and the number of moles of a gas (n); PV=nRT.
Does combined gas law have to be in ATM?
It is crucial to match your units of Pressure, Volume, number of mole, and Temperature with the units of R. If you use the first value of R, which is 0.082057 L atm mol-1K-1, your unit for pressure must be atm, for volume must be liter, for temperature must be Kelvin.
What is meant by ideal gas?
The term ideal gas refers to a hypothetical gas composed of molecules which follow a few rules: Ideal gas molecules do not attract or repel each other. The only interaction between ideal gas molecules would be an elastic collision upon impact with each other or an elastic collision with the walls of the container.
