a)
radiation from the sun
b)
convection from the sun
c)
conduction from the sun

10.
Carolina is boiling water on a stove. When she touches the handle of the pot, she notices it is hot. What is most likely the reason the handle is hot?
a)
The heat from the stove is carried into the pot’s metal handle through radiation.
b)
The heat from the stove is carried into the pot’s metal handle through conduction.
c)
The heat from the stove is carried into the pot’s metal handle through convection.
d)
The heat from the stove is carried into the pot’s metal handle through transpiration.
11.
How are heat from the sun and heat from a campfire alike?
a)
They move by radiation.
b)
They move by convection.
c)
They move by conduction.
d)
They are solar energy.
12.
14. Explain the difference between conduction and convection.
a)
Conduction involves heat going in all directions while heat rises with convection.
b)
Heat moves in all directions for convection, but it rises for conduction.
c)
Heat rises for convection and travels thru liquids and gases. Conduction travels thru solids and liquids but must be touching.
d)
Thermal energy travels thru solids for both conduction and convection; however, conduction involves direct contact.
