Thermal Process Chapter 8 Flashcards
What is thermal equilibrium.
It is a state in which two or more objects have the same temperature and that there is no net transfer of energy between them.
What is thermal conduction?
Thermal condition is a process of energy transfer where energy is transferred through the passing on of vibrational motion from one particle to another.
What is convection?
Convection is a process of energy transfer by means of convection currents of a fluid, due to a difference in density.
What is radiation?
Radiation is the process of energy transfer by electromagnetic waves. It does not require a medium.
What I radiation affected by?
It is affected by the surface temperature, surface area, surface colour and texture.
What are examples of conduction?
Hair dryers
Instant water heater
Thermal wear
Double-/triple-glazed windows
What are examples of convection?
Electric kettles
Hot air balloons
Sea breeze
Land breeze
What are example of radiations?
Greenhouse
Space blanket
Global warming
