Study Notes
Heat Transfer
- Heat is energy transferred between objects due to a temperature difference.
- A thermometer measures temperature.
- Temperature is the degree of hotness or coldness of an object.
- Hot objects have fast-moving particles, cold objects have slow-moving particles.
- Heat transfer occurs in three ways: conduction, convection, and radiation.
Conduction
- Conduction is the primary mode of heat transfer in solids.
- Heat transfer occurs by direct contact between objects.
- Example: holding the handle of a hot pan, ironing clothes, heating coals on an electric stove.
Convection
- Convection is heat transfer by the movement of particles of a fluid (liquid or gas).
- The fluids move due to temperature differences, with warmer fluids rising and cooler fluids sinking.
- Example: boiling water, land and sea breezes, using a hair dryer.
Radiation
- Radiation is heat transfer by electromagnetic waves.
- Heat can transfer with or without a material or medium.
- Example: warming hands near a fire, using a microwave to heat food, sunbathing causing sunburn.
