ملخص الدرس

This lesson introduces the kinetic molecular theory of matter, defining thermal energy as the total internal kinetic energy of constituent particles and temperature as the average kinetic energy per particle. It explains that heating accelerates molecular velocity while cooling decelerates it, defines heat as directional thermal energy transfer from hotter to colder bodies, and establishes Celsius calibration standards ($0^\circ\text{C}$ freezing, $100^\circ\text{C}$ boiling).

هتتعلم إيه فى الدرس ده

• All matter consists of particles in perpetual motion.
• Thermal energy is total particle kinetic energy; Temperature is average particle kinetic energy.
• Heating accelerates particle motion and raises temperature; cooling slows particles and lowers temperature.
• Heat flows spontaneously from hotter to cooler objects; water freezes at $0^\circ\text{C}$ and boils at $100^\circ\text{C}$.
