**Educational Content: Thermodynamics and Properties of Air**- **Understanding Extensive Properties:** - Dividing a system into two equal parts, each part of the property has the same value as the original system. Is this statement an example of an extensive property? - True - False- **Calculating the Properties of Air:** - Evaluate the density, specific gravity, and mass of the air in a room with the following dimensions: 4 m x 6 m x 8 m, at a pressure of 100 kPa and a temperature of 25°C. - A diagram is present showing a rectangular room with dimensions labeled as 4 m, 8 m, and 6 m. The conditions of the air within the room are noted: P = 100 kPa and T = 25°C. - Choices are presented for the calculations: 1. Density: 1.17 kg/m³, Specific Gravity: 0.00117, Mass: 224.64 kg 2. Density: 13.9 kg/m³, Specific Gravity: 0.0139 kg/m³, Mass: 2668.8 kg 3. Density: 1.17 kg/m³, Specific Gravity: 0.00117, Mass: 140 kg 4. Density: 13.9 kg/m³, Specific Gravity: 0.0139, Mass: 2668.8 kgThis information helps students understand the concept of extensive properties and apply calculations of density, specific gravity, and mass in real-world scenarios.
