in the Atmosphere. Thermal Energy Transfer. What is Thermal Energy Transfer?. There are three types of thermal energy transfer: Radiation Conduction Convection. Radiation. Heat transfer by radiation is the transfer of heat through electromagnetic waves.
Thermal Energy Transfer
empty space to earth.
Ultraviolet Light- has a shorter wavelength than visible light and can cause sunburn and skin cancer
Infrared Radiation-has longer wave length than visible light and is felt as heat
Earth’s temperature remains stable because of the balance between the amount of radiation coming from the Sun and the amount going out from Earth.
Land, trees, and the oceans absorb and emit solar radiation mainly in the form of infrared radiation.
Glass allows sunlight into a green house. It prevents infrared radiation from escaping which keeps the greenhouse warm
Certain gases, such as CO2, in the atmosphere act like the glass in a greenhouse warming the atmosphere.
Your Coke becomes cold because the heat from the soda
transfers into the ice, not the other way around.
What is really happening here?
Why do you wear heavy clothes when it’s cold outside?
A breeze makes you feel cooler because the wind transfers heat away from your body.
You feel the cold of a winter day because the cold air transfers into you.
Your Coke in a cooler gets cold because the cold from the ice moves into the Coke.Examples
As air above the road warms up, it becomes less dense and rises and is replaced by
cooler air, forming a convection current.
The radiator warms the room by warming the
air around it. Then the warm air transfers heat
to the rest of the room through convection.
This picture illustrates all three type of heat transfer.
Can you identify them all?
