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

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

A safety audit for the gas-solid fluidization experiment was conducted. The following safety concerns were found when performing the audit: operating beyond the operating limits‚ spillage of the beads‚ risk of head injury from bending over to change the beads in the apparatus or from the low bar‚ and congestion of the workspace. One of the biggest safety concerns with this lab involved the small glass beads that acted as the solid in the experiment. If the gas flow rate goes below 50 standard cubic

Charles’s Law – Lab Report Charles’ Law: Assuming that pressure remains constant‚ the volume and absolute temperature of a certain quantity of a gas are directly proportional. Mathematically‚ this can be represented as: Temperature = Constant x Volume or Volume = Constant x Temperature or Volume/Temperature = Constant Substituting in variables‚ the formula is: V/T=K Because the formula is equal to a constant‚ it is possible to solve for a change in volume or temperature using a proportion

Review Sheet for Gas laws Name ___________________________ 1. A gas at 2.3 atm occupies 12 liters. The volume is changed to 6 liters what is the resulting pressure? 2. A sample of gas is confined to 30ml at a pressure of 6 atmospheres. When the pressure is changed to 3liters‚ what is the resulting pressure? 3. A gas occupies 30 L. When the gas is heated from 50C to 100C‚ what is the final volume? 4. In a lab‚ Neon vapor occupied a volume of 1 liter at STP‚ the volume was changed to 4 liter

Common Name: Pearl Scientific Name: Calcium Carbonate Formula: CaCO3 Fundamental particles: Pearls are comprised of a positive Calcium ion (Ca+) and a negative Carbonate polyatomic ion (CO3+) Usage: Jewelry Properties: Pearls are good jewelry because they are hard and lustrous. Pearls are hard because of the strong Intermolecular forces created between the Calcium and the Carbonate ions. The pearls luster is dependent on the amount of nacre excreted. The Oyster produces nacre when

Induction and Faraday’s Thursday‚ October 25‚ 2012 Lab Report 6 Introduction and Faraday’s Law Objective: In this experiment‚ Faraday’s law of induction will be investigated. Theory: Faraday’s law of induction states the induced emf or voltage in a coil is proportional to the rate of change of magnetic flux through a coil‚ this is shown blew: Ƹ= -dɸ/dt Equation 6.1 The flux of the magnetic field is defined and the following: ɸ=BAcosΘ Equation 6.2

LAB REPORT ON VERIFICATION OF HESS’S LAW Our purpose of doing this lab was to prove the Hess’s law correct. Hess’s law suggests that the enthalpy change of a reaction must be equal to the sum of the enthalpy changes of the related reactions which lead to the original reactions. The following are the reactions at the lab; 1) NaOH ( s) NaOH (aq) 2) NaOH (aq) + HCl (aq) NaCl (aq) + H2O (l) 3) NaOH (s) + HCl (aq) NaCl (aq) + H2O (l) As explained before‚ Hess’s Law states that the enthalpy
