The particulate nature of matter

B: Thermal transfers, greenhouse effect, gas laws, thermodynamics, and circuits.

Calculate thermal energy transfers Use specific heat capacity and latent heat Explain greenhouse energy balance Apply ideal gas relationships Interpret pressure, volume, and temperature data Analyse current, potential difference, and resistance Solve series and parallel circuit problems Calculate electrical power and energy transfer Find density from a mass-volume graph Read two points off a mass-volume graph and find the density as mass over volume (the gradient). Find pressure from a force-area graph Read two points off a force vs area graph (constant pressure) and find the pressure as force over area (the gradient). Find heat capacity from an energy-temperature graph Read two points off an energy vs temperature-rise graph and find the heat capacity as energy over temperature change (the gradient).
