Thermal Energy
Thermal Energy always moves from ________ substances to ____________ substances
warmer, cooler
What drives the motion of matter in a system
Energy
Light and Sound both transmit?
Energy
What are clouds made of?
Water droplets and ice crystals
Melting
change of a solid into a liquid when heat is applied
when thermal energy is transferred via particle collisions
Conduction
What is the energy of motion called?
Kinetic Energy
How does light travel
In a straight line
T or F: If the clouds get thick or high enough, all the light above does not make it through
True
Evaporation
the process in which individual water molecules on the surface of a liquid gain enough motion energy (kinetic energy) to leave the liquid and become a gas
radiation, convection, and conduction
What kind of energy deals with the motion of particles in a substance
Thermal Energy
Name 3 ways light interacts with objects
Reflects, Transmits, and Absorbs
Earthquakes are formed in these crusts along the edges of?
Tectonic Plates (fault lines)
Condensation
the process in which water vapor becomes liquid
What has more thermal energy? An Iceberg or a cup of water?
An iceberg
What is the definition of heat?
a transfer of energy from warmer substances to cooler substances
What must happen for us to see something?
Light must reflect off an object and into our eyes
Span from low to high,
Very tall, high winds flatten the top like an anvil
Can cause violent thunderstorms with heavy rain, hail, and even tornadoes
Cumulonimbus
Solid to gas
Sublimation
What is thermal equilibrium?
When heat flows from a higher temperature object to a lower temperature object until the two objects have an equal temperature
If an ice cube melts in my hand, where did energy move?
From my hand to the ice cube (warmer to cooler)
compression and expansion of air particles creates
sound waves
High
Thin and wispy, most common of the high clouds
Appear during good weather; usually a change coming
Cirrus
What happens to the molecules speed, spacing, and motion in all 3 states of matter
Gas (fast, spread out, move freely)
Liquid (quickly, close together, free to move (not fixed)
Solid (slow, tightly packed, vibrate)
