Heat energy always travels in this direction.
Hot to cold.
Transfer of heat energy through direct contact between two substances is called this.
conduction
A spoon handle in a cup of soup becomes hot because of this heat transfer process.
conduction
Heat energy transfers between two substances by conduction because of this.
The substances are at different temperatures and touching.
The transfer of energy by electromagnetic waves is called this.
radiation
This state of matter has the lowest kinetic energy.
Solid
When a liquid loses enough energy it may change to this state.
solid
When the particles of a gas become more ordered because of a state change, it is called this.
condensing
This state of matter is a highly ionized gas.
plasma
When dry ice gains energy and changes to a gas, it is called this.
sublimation
This state of matter has very little particle motion.
solid
The motion and spacing of the particles of a liquid can be described this way.
Close together and sliding past each other.
Rank the states of matter from least particle movement to most particle motion.
Solid, liquid, gas, plasma
Which of the following shows the particles representing a liquid? B C
B
Bridges have gaps between sections so the road doesn’t buckle because of this.
Thermal expansion
The state of matter with a definite shape and volume.
solid
The state of matter that does NOT have a definite shape, but does have a definite volume.
liquid
The transfer of energy between two substances at different temperatures is called this.
heat
The melting and freezing point of water.
0oC
The total amount of kinetic energy of the particles in a substance.
Thermal energy
This happens to the temperature of a substance when energy is added.
It goes up.
This happens to particle motion when energy is added to a substance.
It goes up.
Particle motion in substances changes because they gain or lose this.
energy
The boiling point of water in oC.
100
The type of heat transfer that occurs through space.
radiation
