Lecture Notes on Thermal Energy Transfer

Vocabulary flashcards covering key concepts related to heat transfer, insulation, and radiation.

Energy Transfer by Conduction

The process by which energy is transferred through a material.

Thermal Conductivity

The higher the thermal conductivity of a material, the higher the rate of energy transfer by conduction.

Metals

Good conductors of energy, allowing for a high rate of energy transfer.

Insulators

Poor conductors of energy, resulting in low energy transfer.

Infrared Radiation

All bodies emit and absorb infrared radiation; the hotter the body, the more it radiates.

Perfect Black Body

An object that absorbs all radiation incident on it.

Specific Heat Capacity

The amount of energy required to raise the temperature of one kilogram of a substance by one degree Celsius.

Loft Insulation

Reduces energy transferred through the roof.

Cavity Wall Insulation

Reduces energy transfer through walls by filling the space between outer and inner walls.

Double Glazing

Reduces energy transfer through windows.
