1.
Convection can occur in
vacuum
solids and fluids
solids only
fluids only
2.
Warm fluid rises because it
has lighter particles
has lower density
has more mass
has no weight
3.
A room heater is most effective when placed
in a vacuum
near the ceiling
near the floor
outside
4.
A sea breeze blows from sea to land in the day because
land heats faster so air above it rises
sea heats faster
wind is generated by tides
land has higher c
5.
Forced convection differs from natural convection in that
it only occurs in solids
it has no energy transfer
it uses a fan or pump
it needs no fluid
6.
A pot is heated at the top by a lamp. Compared with heating at the bottom, the water warms
in the same way
more slowly because no convection current forms
not at all
faster
