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

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

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 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

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

are prime examples of the implementation of gas laws. The physics are based on the simple principle that warm air rises in cooler air. Hot air has less mass per unit of volume. The relevant gas law in use is Charless Law‚ which is V1/T1=V2/T2. The law states that raising the temperature (T1) will also increase the volume (V2)‚ in order to keep the equation true. Generally‚ air is heated through the use of propane burners. When ignited‚ the volume of the gas increases but the balloon cannot expand much

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.
