Students conducted a simple experiment to explore heat transfer. They constructed the closed system you see here: a metal soda can
inside a styrofoam cup. The metal can was filled with 80°C water and placed into the styrofoam cup containing colder water, 10°C.
The students predicted that the water in the metal can would decrease in temperature while the water temperature inside the cup
would increase. Base on the student data recorded in the data table, the prediction was correct. Explain how the transfer of heat
energy occurred. Select ALL the statements that could apply.
A)
Heat energy travels from high to low until equilibrium is met.
B)
Heat is transferred from one location to another via particle collisions.
The hot water had the highest temperature, and the greatest potential
energy
D)
The water in the can had more kinetic energy than the water in the outside
cup
E
Particle collisions transferred that energy from the hot water, to the can,
and then to the cooler water
