Which of the following represents a combination of Boyle’s Law and Charle’s law?
Answer. Combined gas law comes from the combination of Boyle’s law, Charles law and Gay Lussac’s law. According to Boyle’s law, At constant temperature, pressure of a gas is inversely proportional to its volume. HOPE IT HELPS YOU ☺☺ !!!!
Who proposed the combined gas law?
Joseph Louis Gay-Lussac
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.
What is Boyles Law in simple terms?
: a statement in physics: the volume of a gas at constant temperature varies inversely with the pressure exerted on it.
What is K in the combined gas law?
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. … The constant k is a true constant if the number of moles of the gas doesn’t change.6 мая 2019 г.
Why is the combined gas law important?
The combined gas law allows you to derive any of the relationships needed by combining all of the changeable peices in the ideal gas law: namely pressure, temperature and volume.
How is the combined gas law derived?
How is the Combined Gas Law derived? … ∴ PV/T = K ————-(3)(where k is the proportionality sign whose value depends upon mass of a gas and unit of pressure and volume.) Let P1, V1, and T1 be the initial pressure, volume, and temperature (in kelvin scale) respectively.
Do units matter combined gas law?
The constant, k, will also depend on the number of moles and could therefore vary. As long as the number of moles is constant, k will be a true constant value. Any units will work here for pressure and volume but the temperature must be absolute (Kelvin).
What are the units for combined gas law?
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).
