When a substance cools down, its freedom of movement:
decreases
increases
stays the same
When a substance gets colder, its freedom of movement:
increases
decreases
stays the same
When a substance heats up, its freedom of movement:
increases
decreases
stays the same
When a substance gets hotter or warmer, its freedom of movement:
increases
decreases
stays the same
If energy is transferred INTO a substance, the substance will:
get warmer/hotter
get cooler/colder
stay the same
If energy is transferred OUT OF a substance, the substance will:
gets warmer/hotter
gets cooler/colder
stay the same temperature
In the slot canyons, clouds condense from the hot air when...
there is a nighttime decrease in temperature
there is a nighttime increase in temperature
there is a daytime increase in temperature
there is extremely dry weather
In the glacier caves of Iceland, the caves form from glaciers when...
lava heats the rocks of the ground causing the ice touching the ground to melt
lava heats the air causing the top of the glacier to melt
the air condenses into clouds when the nighttime temperature drops
the nighttime drop in temperature causes the glacier to freeze
Niagara Falls can sometimes freeze when...
temperatures drop below freezing during winter
the temperatures drop at nighttime
the volcanic rocks heat up the water
there is a full moon
The "Old Faithful" geyser in Wyoming erupts because...
volcanic rocks heat up the water until it boils and explodes out of the ground
volcanic rocks melt ice underground
wintertime causes water underground to evaporate
nighttime causes water underground to boil
If you want to MELT a solid, you have to:
transfer energy INTO it
transfer energy OUT of it
keep the energy the same
transfer energy both INTO and OUT of it at the same time
If you want to EVAPORATE a liquid, you have to:
transfer energy INTO it
transfer energy OUT of it
keep the energy the same
transfer energy both INTO and OUT of it at the same time
If you want to FREEZE a solid, you have to:
transfer energy OUT of it
transfer energy INTO it
keep the energy the same
transfer energy both INTO and OUT of it at the same time
If you want to CONDENSE a gas, you have to:
transfer energy OUT of it
transfer energy into it
keep the energy the same
transfer energy both INTO and OUT of it at the same time
When energy is ADDED to a substance, it leads to:
an INCREASE in the kinetic energy of the molecules that make up that substance
a DECREASE in the kinetic energy of the molecules that make up that substance
NO CHANGE in the kinetic energy of the molecules that make up that substance
BOTH a simultaneous INCREASE and DECREASE in the kinetic energy of the molecules that make up that substance
When energy is REMOVED from a substance, it leads to:
a DECREASE in the kinetic energy of the molecules that make up that substance
an INCREASE in the kinetic energy of the molecules that make up that substance
NO CHANGE in the kinetic energy of the molecules that make up that substance
BOTH a simultaneous INCREASE and DECREASE in the kinetic energy of the molecules that make up that substance
An INCREASE in molecules' motion is evidence that:
their kinetic energy has INCREASED.
their kinetic energy has DECREASED.
their kinetic energy has STAYED THE SAME.
A DECREASE in molecules' motion is evidence that:
their kinetic energy has DECREASED
their kinetic energy has INCREASED
their kinetic energy has STAYED THE SAME
A "measure of how hot or cold something is" is called:
temperature
heat
kinetic energy
potential energy
The "measure of the average kinetic energy of the molecules of a substance" is also known as:
temperature
heat
potential energy
speed
