Thermal Energy
Kinetic Energy
Particle Energy
Temperature of a material depends upon the average —————— of its particles
Kinetic energy
Thermal energy

Particle energy
the average kinetic energy of the particles in iced tea is —————than the average kinetic energy of the particles in hot tea.
louder
Prettier
Higher
Lower
Thermal energy is transferred from————-
A cooler object to a hotter one
A hotter object to a cooler one
Thermal Energy depends upon the energy of the particles as well as the number of particles.
Which would have more thermal energy, a small cube of Ice at zero Celsius or a large cube of ice at zero Celsius?
The large ice cube because it has more particles than the small ice cube
The small cube of ice because it will melt faster than the large ice cube
Neither, they are cold so they do not have thermal energy
both have the same thermal energy because they are both at zero Celsius.
The movement of thermal energy from a hotter object to a colder one is called
Motion
Kinetic energy
Temperature
Heat

Lower
Faster
Higher
Slower
While temperature refers to an average of the kinetic energy of particles, thermal energy refers to ———— kinetic energy

Which sample has molecules with more average kinetic energy ?
Sample B, because it has more molecules
Sample A because it has faster moving molecules
Sample A because it has yellow molecules
Sample B because it has brown molecules
Which sample has the higher temperature?
Sample B because it has more thermal energy and more molecules
Sample B because the molecules are brown
Sample A because the molecules are moving faster and have more average kinetic energy
Sample A because yellow is such a hot color
If you brought sample A and B close together , in what direction would heat be transferred?
From sample A to sample B
From sample B to sample A
Heat would not be transferred.
sample A and sample B would both transfer heat to each other.
In this picture, heat is being transferred from sample B to sample A. When will the heat transfer stop?
Heat transfer will keep on until object B has zero thermal energy
Heat transfer will not stop, it will keep going
Heat transfer will stop when sample A and sample B have reached the same temperature.
even though sample A has a higher temperature, sample B has a higher thermal energy. Pick the correct explanation from the choices below
the molecules in sample B are brown and have high energy
the molecules in sample A are yellow and have low energy
thermal energy is higher when temperature is lower
there are many more molecules in sample B which make the total energy higher
