Radiation, Convection, and Conduction
when air or water is heated, its density decreases and the air or water rises
What is an explanation for the movement of air and water in currents?
convection
a forced-air furnace blows heated air around the house
conduction
a thermometer under your tongue shows that you have a high fever
convection
heat in the room moves with the warm currents from warmer areas to cooler areas
convection
heat is transferred by the movement of matter
rises, sinks, convection
in a room, warm air _______________ and cold air _______________, this process is called ________________
convection
ocean currents warm colder water
radiation
on cloudless nights, heat escapes from our planet and goes into empty space
radiation
the sun transfers its heat to our planet through space
radiation
the sun warms your face
convection
thermal energy is transferred through matter from particle to particle
radiation
thermal energy is transferred without matter
conduction
two objects at different temperatures are in direct contact
convection
warm water rises in a lake. cold water descends
radiation
you feel the heat of a wood stove when you stand next to it
conduction
you place your cold hands under warm water
conduction
you placed a spoon into a cup of cocoa and it gets hot over time
conduction
you stir hot stew with a spoon. The handle of the metal spoon gets hot.
conduction or convection
you warm up your soup in a pan on the stove
conduction
your feet burn when you walk barefoot across hot sand
convection
The troposphere gets most of its heat through the process shown in the diagram. What type of heat transfer is represented?
