Transcript Total energy of particles

Total energy of particles:
Thermal Energy
Conservation of Energy
• No Energy destroyed
Movement of Thermal Energy
• Heat
Heat Transfer without particle
movement.
• Conduction
Heat transfer occurs from:
• Hot to Cold
Addition or loss of thermal energy
changes arrangement of particles
during:
• Change of State
Temperature of Solid to Liquid
• Melting Point
Vaporization at Surface
• Evaporation
Expansion of Matter when heated:
• Thermal Expansion
Heated Air from Baseboard Heaters:
• Convection
Kinetic Energy of Particles:
• Temperature
Characteristic Property of Liquid:
• Boiling Point
How much matter an object contains?
• Mass
Mass in a given Volume:
• Density
Elements are composed of:
• Atoms
A group of atoms:
• Molecule
Substances not chemically combined:
• Mixture
How are liquid water, ice, and water
vapor different ?
• Different states of matter
Distance is changing, an object is in:
• Motion
Speed is:
• Distance / Time
You know speed and direction you
know:
• Velocity
Graphing Motion the steepness of the
slope shows how:
• How quickly or slowly the object is moving.
Distance vs time graph a horizontal
line shows:
• Object is not moving
300 kilometers in 3 hours you can find:
• Average Speed
When Speed vs Time graph is a
straight line:
• Acceleration is constant
Model where Earth is at the center of
the system of planets is:
• Geocentric system
The heliocentric system was supported
by Galileo when he discovered:
• The phases of Venus
Day and night are caused by:
• Earth’s Rotation
Earth has seasons because:
• Earth’s axis is tilted as it moves around the
sun.
The phase of the moon you see
depends on:
• How much of the sunlit side of the moon faces
Earth.
During a Solar Eclipse:
• The moon is directly between Earth and the sun.
Phase of the moon during lunar
eclipse:
• Full Moon
Tides are caused by:
• Differences in how much the moon pulls on
different parts of Earth.
You are less likely to see a solar eclipse
than a lunar eclipse because:
• You must be in the moon’s shadow to see a solar
eclipse.
Process that moves weathered rock:
• Erosion
Erosion when runoff flows in thin
layer:
• Sheet Erosion
Wind removes surface materials:
• Deflation
Mechanical weathering rock is worn
away by grinding of other rocks:
• abrasion
Earth’s Layers (From Surface)
• Crust, Mantle, Outer Core, Inner Core
Transfer of Energy through empty
space:
• Radiation
Heat Transfer within a fluid:
• Convection Currents
The point beneath Earth’s surface
where rock breaks to trigger
earthquake:
• Focus
Risk of earthquakes on the Pacific
Coast is high because:
• That is where the North American and Pacific plates
meet.
Volcanic belts form along:
• The boundaries of the Earth’s plates.
The volcanoes along converging
oceanic plate boundaries may form:
• An island arc
A volcano that may erupt in the distant
future is:
• dormant
The place where an organism lives:
• Habitat
Environmental Factor that prevents a
population from increasing:
• Limiting Factor
An organism’s role:
• Niche’
Study of how things interact with each
other and their environment:
• Ecology
