#### Which equation represents the combined gas law?

## Which equation is derived from the combined gas law Brainly?

Answer. The volume of a fixed mass of gas is inversely proportional to its pressure at constant temperature . This is known as Boyle’s law. P1 V1=P2 V2 PV =a constant P inversely proportional to 1/V at constant T.

## What is N in the combined gas law?

n = # of moles (mol) R = the Ideal Gas Law Constant. T = Temperature in Kelvin (K) The value n is the amount of the gas measured as moles.

## How can Charles law be derived from the combined gas law?

If the temperature is constant, as the pressure of a gas increases, the volume decreases. Explain how Charles’s law can be derived from the combined gas law. Divide both sides of the equation by P1, P1 and P2 will cancel leaving you with the equation for Charles’s law.

## Which law states that the pressure and absolute temperature?

Gay-Lussac’s Law

## 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). R has the value 8.314 J/(K·mol) ≈ 2 cal/(K·mol), or 0.0821 l·atm/(mol·K).

## How does the combined gas law work?

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 ∝ 1 P at a constant T .

## Does the combined gas law need to be in ATM?

The Gas Constant (R) 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^{–}^{1}K^{–}^{1}, your unit for pressure must be atm, for volume must be liter, for temperature must be Kelvin.

## 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.

## What are the variables in the combined gas law?

However, situations arise where all three variables change. The combined gas law expresses the relationship between the pressure, volume, and absolute temperature of a fixed amount of gas.

## What three factors that affect gas does the combined gas law include?

The three fundamental gas laws discover the relationship of pressure, temperature, volume and amount of gas. Boyle’s Law tells us that the volume of gas increases as the pressure decreases. Charles’ Law tells us that the volume of gas increases as the temperature increases.
