Pressure Gay-Lussac’s law

Louis Gay-Lussac continued the ballooning exploits initiated by Charles, ascending to over 20,000 feet in a hydrogen balloon in the early 1800s. Gay-Lussac s law defines the relationship between the pressure and temperature of an ideal gas. If the temperature of the air in the syringe increases while keeping the volume constant, the gas particles speed up and make more collisions with the inside walls of the syringe barrel. As we have seen, an increase frequency in the number of collisions of the gas particles with a container s wall translates into an increase in pressure. Gay-Lussac s law says that pressure is directly... [Pg.105]

Charles law, also known as Gay-Lussac s law, states that the volume of a given mass of gas varies directly as the absolute temperature if the pressure remains constant, that is. [Pg.528]

The interaction forces which account for the value of a in this equation arise from tire size, the molecular vibration frequencies and dipole moments of the molecules. The factor b is only related to the molecular volumes. The molar volume of a gas at one atmosphere pressure is 22.414 ImoD at 273 K, and this volume increases according to Gay-Lussac s law with increasing... [Pg.112]

According to Gay-Lussac s Law, we can think directly in volumes instead of moles or molecules if the temperature and pressure are constant during a reaction. [Pg.194]

In order to work out reacting volumes of gases, we can use Gay-Lussac s law of combining volumes When gases react they do so in volumes which bear a simple ratio to each other and to the volumes of the products if they are gases, all measurements of volume being at the same temperature and pressure . [Pg.24]

Gay-Lussac s law describes the relationship between the pressure of a gas and its Kelvin temperature if the volume and amount are held constant. Figure 8.5 represents the process of heating a given amount of gas at a constant volume. [Pg.107]

Gay-Lussac s law—The pressure and temperature of a gas are directly proportional if the amount and volume are constant. [Pg.121]

Gay-Lussac s Law law that states the pressure of a gas is directly proportional to the gas s absolute temperature Gay-Lussac s Principle law that states when a chemical reaction takes place involving gases, the volumes of reactants and products are in small whole number ratios... [Pg.341]

Boyle (1662) observed that at constant temperature the volume of a sample of gas varies inversely with pressme, but Boyle did not explain why this was so. Somewhat later. Charles (1787) refined the observation to the effect that the volume of any sample of a gas vanes directly with the absolute temperature provided thal the pressure is held constant. A few years later, Gay-Lussac (1808), in reporting the results of his experiments with reacting gases, observed that volumes of gases that are used or produced in a chemical reaction can be expressed in ratios of small whole numbers—a concept to become known as Gay-Lussac s law of combining volumes. It should be noted that tlie foregoing concepts proposed by Boyle, Charles, and Gay-Lussac were based upon experimental observations, not on theory. [Pg.159]

GAY-LUSSAC S LAW. A modification of Charles law to state the following At constant pressure the volume of a confined gas is proportional to its absolute temperature. The volumes of gases involved in a chemical change can always be represented by the ratio of small whole numbers. [Pg.706]

Gay-Lussac s law states that at constant volume and number of moles, the pressure of a gas is proportional to the absolute temperature ... [Pg.47]

Gay-Lussac s law describes the effects of pressure and temperature—volume is constant. The law states that the pressure of the gas varies directly with the absolute temperature. [Pg.65]

Problem 1.9 contains the calculation showing that 1 atm is equal to 14.7 psi. Making the conversion, we find that the beginning pressure was (30.0 + 14.7)psi and that the tire pressure at the end of the trip was (34.2 + 14.7)psi. Since absolute zero is —460°F (Fig. 1-1), the absolute temperature is (27 + 460) Fahrenheit degree intervals. Applying Gay-Lussac s law, which determines temperature and pressure changes with no volume changes,... [Pg.69]

Gay-Lussac s law states that the pressure of a fixed amount of gas in a fixed volume is proportional to absolute temperature, or ... [Pg.81]

Changes in temperature or pressure can be found using Gay-Lussac s law. [Pg.81]

Example A 2.25 L container of gas at 25°C and 1.0 atm pressure is cooled to 15°C. How does the pressure change if the volume of gas remains constant Solution This is a pressure-volume change so use Gay-Lussac s law. [Pg.81]

From your understanding of how molecules respond to heat and cold, what happens to the pressure of an enclosed gas when heat is applied As you can imagine, intense pressure builds up as the gas molecules move faster and strike the walls of the container more often and with more force. Gay-Lussac s Law states that temperature and pressure are directly proportional As one increases, so does the other. [Pg.75]

Equation 8.5) Pressure and Temperature Relationships You may have noticed that volume appears in both Boyle s and Charles s laws. If we know that pressure and volume are inversely related and volume and temperature are directly related, then we can say that pressure and temperature are inversely related, or as in Equation 8.5 P — = constant T This relationship is frequently referred to as Gay-Lussac s Law, named after Joseph Louis Gay-Lussac, one of the early gas researchers. Gay-Lussac also performed some experiments that helped Amadeo Avogadro create what is now referred to as Avogadro s law. [Pg.154]

Gay-Lussac s law states that pressure and temperature are directly proportional at constant volumes. [Pg.176]
