Q3: A gas contained in a vertical piston-cylinder assembly. A vertical shaft whose cross- sectional area is 0.8 cm2 is attached to the top of the piston. The total mass of the piston and F-1334 N A-0S cm I bar shaft is 25 kg. While the gas is slowly heated, the internal energy of the gas increases by 0.1 kJ, the potential energy of the piston-shaft combination increases by 0.2 kJ, and a force of 1334 N is exerted on the shaft as shown in the figure. The piston and cylinder are poor conductors, and friction between them is negligible. The local atmospheric pressure is 1 bar and g = 9.81 m/s². Determine, (a) the work done by the shaft, (b) the work done in displacing the atmosphere, and (c) the heat transfer to the gas, all in kJ. FD- 10 cm Gas Answer: 1.094 kJ, 0.637 kJ, 2.031 kJ

6. Relating Heat and Work to Changes of Internal Energy Gases A(g) and B(g) are confined in a cylinder-and-piston arrangement like that in Figure 5.4 (see below) and react to form a solid product C(s): A(g) + B(g) → C(s). As the reaction occurs, the system loses 1150 J of heat to the surroundings. The piston moves downward as the gases react to form a solid. As the volume of the gas decreases under the constant

Heat Capacity We define q, the amount of (energy transferred as) heat as directly proportional to the temperature change (AT): q-CAT where C is a positive constant (called the heat capacity of the sample). We can see from this equation that the larger the temperature change is (for a given sample), the more heat must have been transferred. If AT-1° C, then q and C are numerically equal; thus, heat capacity can be defined as the amount of heat needed to cause a temperature change of 1 : °C By convention AT is calculated by subtracting the initial temperature from the final temperature. AT = Tfinal - Tinitiat %3D Therefore, for a sample that warmed up, the algebraic sign of ATis positive • and the algebraic sign of q is positive For a sample that cooled down, the algebraic sign AT is negative and the algebraic sign of q is negative If the temperature of a sample decreased from 20.00°C to 18.00°C, then (in degrees Celsius) is AT - 18,00 : "c- 20.00 : °C = 2.00 : C In Kelvin, AT -( 18.00 •…
