GAS LAWS Properties of Gases Gases expand into any available volume • gas molecules escape from open containers. Gases are completely miscible • once mixed they will not spontaneously separate. Gases are described in terms of T‚ P‚ V and n Volume‚ Amount and Temperature • A gas expands uniformly to fill the container in which it is placed – The volume of the container is the volume of the gas – Volume may be in liters‚ mL‚ or cm3 • The temperature of a gas must be indicated

Purpose: Unknown mixtures will be separated by means of chromatography in which the mixture will be passed in a solution through a medium leaving behind components of the mixture at different rates‚ therefore‚ different spots on the absorbing substance. This will help determine the identity of unknown mixtures. The spot colors on the strip of filter paper and the Rf values of the unknown samples will be compared to those of known samples. To find the position of the spots on the strip of paper‚ we

Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of the gas is reduced. The particles in a gas are further apart than

GAS LAWS GROUP 1 Sheena Mae Agustin Hans Alcantara Renzo Bren Ado Miguel Afable Ron J Advincula De La Salle University - Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT Gases behave in a similar way over a wide variety of conditions because to a good approximationthey all have molecules which are widely spaced‚ and nowadays the equation of state for an ideal gas isderived from kinetic theory. The combined gas law or general gas equation is formed by the combination of

Gas laws have an impact on several aspects of our lives. The S.T.E.M I decided to explore deals a great deal in thermodynamics in the gas law I chose chemistry. First off I have to explain what is the broad practice of chemistry. Chemistry‚ a branch of physical science‚ is the study of the composition‚ properties and behavior of matter. Chemistry is concerned with atoms and their interactions with other atoms‚ and particularly with the properties of chemical bonds. Chemistry is also concerned with

First Law-Exercise: Problem 1: A volume 10 m3 contains 8 kg of oxygen at a temperature of 300 K. Find the work necessary to decrease the volume to 5 m3‚ (a) at a constant pressure and (b) at constant temperature. (c) What is the temperature at the end of the process in (a)? (d) What is the pressure at the end of process in (b)? (e) Show both processes in the p-V plane. Problem 2: The temperature of an ideal gas at an initial pressure p1 and volume V1 is increased at constant volume until the pressure

Gas Laws Name Institution The 3 Gas Laws Introduction The three gas laws include: Gay-Lussac’s law‚ Boyle’s law and Charles’ law. When combined with Avogadro’s law the three laws can be generalized by the ideal gas law. Gases possess observable properties which include‚ mass‚ pressure (P)‚ thermodynamic temperature (T) and volume (V). These properties are related to each other and the state of a gas is determined by their values. The three laws are derived from these properties. Discussion

Bolye’s Law Problems Example: If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L‚ what will the new pressure inside the piston be? • Read the problem and determine what is given and what is unknown? • Decide which law to use. • Substitute the values (given numbers) from the problem into the equation Given: P1 = 1.5 atm Unknown or find: P2 = ? = X V1 = 5.6 L

Boyle’s Law - Solutions 1) If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L‚ what will the new pressure inside the piston be? P1V1 = P2V2 (1.5 atm)(5.6 L) = (x)(4.8 L) x = 1.8 atm 2) I have added 15 L of air to a balloon at sea level (1.0 atm). If I take the balloon with me to Denver‚ where the air pressure is 0.85 atm‚ what will the new volume of the balloon be? P1V1 = P2V2 (1.0 atm)(15 L) = (0.85 atm)(x) x = 18

The gas in the natural world follows the specific laws. Different laws have their own explanations and they apply to the real things in this real world. Charles’s Law‚ Boyle’s Law‚ Combined Gas Law‚ Avogadro’s Law and Gay-Lussac Law explain the gas properties and show the scientists how the gas functions. Charles’s Law describes how gases tend to expand when the heat is added. When the temperature increases‚ the volume of the gas increases.
