Use the photo to complete the statement.
The process shown in the photo is _____
heat transfer by direct contact.
movement of molecules by vibration.
heat transfer by radiation.
movement of molecules by conduction.
movement of molecules by conduction.
To determine the correct answer, let's analyze the photo. In the photo, there appears to be a solid object touching another solid object. This indicates that there is direct contact between the two objects.
Based on this observation, we can conclude that the process shown in the photo is the movement of molecules by conduction. Conduction is the transfer of heat between objects that are in direct contact with each other. In this case, the heat is being transferred through the direct contact of the molecules in the solid objects.
Therefore, the correct completion of the statement is:
The process shown in the photo is movement of molecules by conduction.
