None of the above.

The molecules changed to gas phase and moved around in place.

The molecules changed to solid phase and moved around in place.

The molecules changed to liquid phase and moved around each other.

The molecules changed to gas phase and moved away in place.

Its energy decreases while the energy of the glass decreases.

Its energy increases while the energy of the glass decreases.

Its energy stays the same while the energy of the glass decreases.

It is impossible to know without data on the number of molecules in

Direct contact is not required for conduction or radiation

Direct contact is required for conduction, but not for radiation.

Conduction causes temperature to rise, but not for radiation.

Radiation causes temperature to rise, but not for conduction.

Both will be the same temperature, because both bottom bricks transferred the same amount of energy.

Sheila's top brick was will be cooler, because the energy that transferred to Sheila's top brick was spread out with more molecules.

Ralph's top brick was cooler, because less energy has to transfer to Ralph's top brick.
