What we have learnt

  • Thermal physics investigates heat, work, and temperature and their impact on matter.
  • Temperature measures the average kinetic energy of particles, affecting heat flow direction.
  • Heat is defined as energy transfer resulting from temperature differences, not a property of an object.

Key Concepts

-- Temperature
A measure of the average kinetic energy of the particles within a substance.
-- Heat
The transfer of thermal energy from a higher temperature area to a lower temperature area.
-- Specific Heat Capacity
The amount of thermal energy required to raise the temperature of 1 kilogram of a substance by 1°C.
-- Phase Change
A physical process in which a substance transitions between different states of matter, involving energy transfer.
-- Latent Heat
The thermal energy absorbed or released during a phase change at constant temperature, not changing the temperature.
