Physics - Thermodynamics - Temperature and heat - Temperature and Heat Explained
A 4-step lesson. Step 1: 'Temperature is a measure of the AVERAGE kinetic energy of particles in a substance. Hotter = particles moving faster.' Scales: Celsius (water freezes 0°, boils 100°), Kelvin (0K = absolute zero, no particle motion. K = °C + 273). Step 2: 'Heat (thermal energy) is the TOTAL
