1
Kinetic Energy and Temperature

2
Kinetic Energy
energy possessed by an object in motion
3
Heat
thermal energy transferred between two objects
heat flows from hotter object to colder object
4
Multiple Choice
The energy associated with motion is called
kinetic energy
elastic potential energy
gravitational potential energy
nuclear energy
5
Multiple Choice
Thermal energy is
the energy of motion
energy of nuclear processes
an indication of a physical change
heat energy
6
Multiple Choice
Hot objects begin to cool as
cooler air is transferred to the hot object
atoms in the object react with the oxygen in the air
thermal energy in the object is transferred to the surrounding air
thermal energy in the object cancels out energy in the air
7
Temperature
related to the average kinetic energy
measure of how hot or cold an object is
increase temperature causes an increase of average kinetic energy
decrease in average kinetic energy causes a decrease in temperature
8
Temperature
measured in Celsius, Fahrenheit or Kelvin
Celsius: water freezes at 0 ° C and boils at 100 ° C
Fahrenheit: water freezes at 32 ° F and boils at 212 ° F
Kelvin: water freezes at 273 K and boils at 373 K
9
Multiple Choice
At higher temperature
particles in an object have less kinetic energy
particles in an object move faster
a gas contracts
particles in ab object move slower
10
Multiple Choice
Which of the following is TRUE when particles GAIN thermal energy?
particles move more slowly
particles stop moving
particles move further apart
particles move closer together
11
Multiple Choice
What happens to particle movement/speed when energy is removed?
particles slow down
particles go faster
particles don't move
particles stay the same speed
12
Multiple Choice
The temperature of a substance increases as
the substance expands
the substance's volume increases
the substance's mass increases
the average kinetic energy of its particles increases
13
Multiple Choice
Particles are always moving
true
false
14
Multiple Choice
If particles of two substances have the same average kinetic energy, then
the specific heats of the substances are identical
the particles will not react chemically
the substances have equal thermal energies
the substances have equal temperatures
15

heat
radiation
conduction
convection
