An ideal diatomic gas initially has a pressure of 5 2.00x10^5Pa, a volume of 4.00m^3 and a temperature of 27 C . It has an adiabatic change in pressure to 6.00x10^5 Pa. a. What are the new volume and temperature? b. What is the change in internal energy of the gas?
When gas expands in a cylinder with radius r, the pressure P at any given time is a function of the volume V: P = P(V). The force exerted by the gas on the piston (see the figure) is the product of the pressure and the area: F = πr²p. piston head V x The work done by the gas when the volume expands from volume V₁ to volume V2 is as follows. 1 W = dv In a steam engine the pressure and volume of steam satisfy the equation PV1.4 = k, where k is a constant. (This is true for adiabatic expansion, that is, expansion in which there is no heat transfer between the cylinder and its surroundings.) Calculate the work done by the engine during a cycle when the steam starts at a pressure of 180 lb/in² and a volume of 500 in³ and expands to a volume of 700 in³. (Round your answer to two decimal places.) W = X ft-lb
Answers (~1.9kJ, ~1.1kJ, ~4kJ) The figure to the right shows a gas contained in a vertical piston-cylinder assembly. A vertical shaft with a cross- sectional area of 1.0 cm² is attached to the top of the piston. The total mass of the piston and shaft is 35 kg. While the gas is slowly heated, the internal energy of the gas increases by 0.25 kJ, the potential energy of the piston-shaft combination increases by 0.5 kJ, and a force of 1300 N is exerted on the shaft as shown in the figure. The piston and cylinder are both good insulators and friction between them is negligible. The local atmospheric pressure is 1 bar and g = 9.81 m/s². Determine: 21 F-1300N (c) the heat transfer to the gas (kJ) (d) Provide a detailed accounting of where all of the heat energy has gone.

Hydrogen gas is enclosed in a chamber at 200 degrees C and a volume of 0.0250 m3. Initially, the pressure in the gas is 1.50 x 106 Pa. The chamber is removed from the heat source and allowed to cool until the pressure in the gas falls to 0.950 x 106 Pa. What is T2?
