of ideal gas. Tasks: 1) To learn the Kleman – Dezorm method; 2) To determine the rate of adiabat for air using the Kleman – Dezorm method. Experiment To define the adiabat of the air [pic] in this work it is used the classical Kleman – Dezorm method. Initially, the system (gas) is in state 1, which is characterized by thermodynamic parameters: temperature T1, pressure p1 and specific volume v1 (volume of unit of mass of gas). Making the adiabatic expansion process gas transfers

specific volume of the saturated liquid, vf = 0.0008580 m3/kg at 900 kPa. We can then find the mass as follows. We can now compute V2 = mv2 and find the work done. W = 5,571 kJ 2 A mass of 2.4 kg of air at 150 kPa and 12oC is contained in a gas-tight, frictionless piston-cylinder device. The air is now compressed to a final pressure of 600 kPa. During the process, heat is transferred from the air such that the temperature inside

Airbags are safety features that are designed to save passengers from harm in a head-on collision. Airbags react within milliseconds of a crash, and the folded nylon bag quickly becomes inflated with nitrogen gas. The inflated airbag has the role of being a cushion for passengers and prevents them from hitting into the steering column and dashboard, which can cause painful injuries for passengers. Airbags were invented by John Hetrick in 1953 after Hetrick, his wife and young daughter got

discovered that when held at a constant temperature, the volume and pressure of a gas are inversely proportionate. Put simply, when the volume goes up, pressure drops, and vice versa. The mathematic equation is equally as simple: PV=K where P=Pressure, V=Volume, and K is simply a constant. This has become a basic principle in chemistry, now called "Boyle's law" and is included as a special case into the more general ideal gas law. Spray paint uses a real
