The relationship between the temperature of a system and the total energy of the system depends on what factors?
Whether or not all the parts of the system are connected
The ability of scientists to accurately measure the thermal energy of the system
Whether or not the system is in motion at the time
The type, states, and amount of matter in the system
Four metal cubes, each at a different starting temperature, are placed in contact with each other.
Which of the following describes the most likely flow of thermal energy in this situation?
Cube #4 to Cube #2
Cube #1 to Cube #2
Cube #3 to Cube #4

Students are testing different materials to find the one that transfers the most heat energy. Identical containers, made of the different materials, were filled with hot water, and the temperature of the water was measured and recorded over time.
Based on the graph of the time and temperature data, which material was most effective at transferring thermal energy?
1
2
3
4
An investigation to determine which material can maximize heat energy transfer would most likely include which of the following?
Hot water placed in containers made of different substances
Ice cubes sealed in containers of various sizes
Metal objects heated to a variety of temperatures
Air temperature recorded at different times of day
A ball rolls across the floor. Because of friction, the ball will eventually slow down and come to a stop. Which of the following is evidence of energy transfer resulting from the change in the motion of the ball?
Different surfaces create different amounts of friction.
The ball moves in the same direction as it rolls across the floor.
Energy sets the ball in motion.
The ball and the floor gain a small amount of heat energy.
A graph showing the kinetic energy of a 10 kg object at different speeds is provided.
