ملخص الدرس

This lesson concludes Concept 2.1 by demonstrating how industrial manufacturing exploits thermal energy and phase transitions. It examines high-temperature glassblowing (melting silica and molding upon cooling), polymer injection molding, metal alloying in metallurgy, and introduces cutting-edge Phase Change Materials (PCMs) in smart thermoregulatory textiles.

هتتعلم إيه فى الدرس ده

• Glassblowing melts sand silica at $>1500^\circ\text{C}$ to shape liquid glass that solidifies upon cooling.
• Thermoplastics are melted and injected into molds to mass-produce solid components.
• Metallurgy melts metals to produce high-strength alloys (steel, bronze).
• Smart fabrics utilize Phase Change Materials (PCMs) to absorb and release body heat dynamically.
