Base your answer to the question on the diagram above, which shows insulated styrofoam cups of water connected by an aluminum bar. The thermometers show the temperatures of the cups A and B at the beginning of a heat flow experiment. Over the next 15 minutes, which changes would most likely occur?
The temperature in cup A will decrease and the temperature in cup B will increase.
The temperature in cup A will decrease and the temperature in cup B will decrease.
The temperature in cup A will increase and the temperature in cup B will increase
The temperature in cup A. will increase and the temperature in cup B will decrease.
The reason the temperature in the cups in the experiment above changes is because aluminum is
thermally expanding
a conductor
an insulator
a nonmetal

When heat is passed on by direct contact of particles, this occurs
conduction
condensation
convection
radiation
A material that doesn’t allow heat to pass through it easily is a/an
conductor
insulator
metal
rock
Movement that transfers heat in a fluid is called
conduction
convection
radiation
specific heat
When molecules in an object move faster, they have more _______.
potential energy
kinetic energy
