Energy
The Sum of kinetic and potential energy of the particles that make up an object is what?
Thermal Energy
How easy it is to heat a material. Conductors have a low this and insulators have a high this.
Specific Heat
A change in the state of matter will occur if enough __________ is added or removed from an object.
Thermal Energy
Matter with a definite shape and volume
Solid
Matter with no definite volume nor definite shape.
Gas
Heat
The transfer of thermal energy from one material to another by electromagnetic waves. Does not need matter.
Radiation
Snow forms in clouds because water vapor changes directly to ice (solid). What is this an example of?
Deposition
Matter has a definite volume but to definite shape
Liquid
Particles are closer together because attractive forces are strong.
Solid
The average kinetic energy of the particles of an object.
Temperature
Materials like metals through which thermal energy transfers easily.
Thermal Conductors
A puddle disappears on a hot day. What process is this?
Evaporation or vaporization
During thermal expansion the volume ____________
increases
During thermal contraction causes the volume to ____________
decrease
The transfer of thermal energy by the movement of particles from one part of a material to another.
Convection
Materials like foam or cloth through which thermal energy does not transfer easily.
Thermal insulator
Condensation
During thermal expansion the particles __________
spread out
During thermal contraction the particles ____________
Get closer together
The transfer of thermal energy between materials by the collisions of particles.
At which temperature would particles of a substance be moving the fastest. 20 Degrees, 34 Degrees, 58 degrees.
58 degrees, It is the hottest
Dry ice forms a gas right from a solid. What process is this?
Sublimation
During thermal expansion the speed of the particles____________
increase
During thermal Contraction the speed of the particles ___________
decreases
