Responses

Thermal energy does not flow between the two flasks.
Thermal energy does not flow between the two flasks.

Thermal energy flows from the flask with room temperature water to the flask with hot water.
Thermal energy flows from the flask with room temperature water to the flask with hot water.

Thermal energy flows equally between the two flasks.
Thermal energy flows equally between the two flasks.

Answer 1

Thermal energy flows from the flask with hot water to the flask with room temperature water. This is because heat naturally transfers from a hotter object to a cooler object until thermal equilibrium is reached. So the correct response is:

Thermal energy flows from the flask with hot water to the flask with room temperature water.

Conduction

Answer 3

The type of energy transfer that can take place without matter present is radiation.

Radiation transfers energy through electromagnetic waves and does not require a medium (such as air or water) to travel through. Therefore, the correct response is:

Radiation.
