THERMAL PHYSICS LABORATORY: INVESTIGATION OF ADIABATIC PROCESSES IN AIR This experiment has two parts. In the first‚ you will use a dynamic method to measure the ratio of the specific heat capacities of air and‚ in the second‚ you will investigate the behaviour of gas undergoing an expansion that is approximately adiabatic and ‘partially reversible’ – somewhere between the two limits of a completely irreversible (free) and perfectly reversible expansion. The air can be considered an ideal gas

Chemistry 222 – Lab 4 Decomposition of Hydrogen Peroxide Abstract: This lab was designed to observe the decomposition of hydrogen peroxide into it oxygen and water. The equation for this reaction is H202 H2O + +1/2O2 thus by measuring volume and pressure of O2 generated the amount of O2 generated can be calculated which in turn can be utilized to determine the concentration of water already in the H2O2 solution. The results determined that 3.02% of the solution is composed of H2O2. Introduction:

changing the pressure inside of the tube)‚ so that we could transport the remaining water to a graduated cylinder. When doing this‚ it was very important that the water level inside of the tube was equal to that of the surrounding water in the bucket‚ because that ensured that since the water pressure in the tube was the same as that of the surrounding water‚ the pressure of the gas would be the same as that of the surrounding air. Thus‚ we recorded the gas pressure to be the same as the pressure in the

In simple terms‚ secondary recovery is the addition of basic water flood or gas flood (i.e.‚ pressure maintenance) as a continuous force. Secondary recovery methods should be introduced very early in the life of a field while the income and profits from the wells are high enough to pay for the additional equipment and installation costs. As noted in the following sections‚ there

determining the volume of a known amount of gas (H2) at a measured temperature and pressure. Determination of Whether Boyle’s Law Applies to Air Boyle’s Law states that for a fixed amount of gas at constant temperature‚ the pressure of the gas will vary inversely with the volume so that P ∝ 1/V or PV = a constant (if n and T are constant). To determine whether this relationship holds for a mixture of gases‚ the pressure of a fixed amount of air (which is a mixture of gases) will be measured as the
