Thermodynamics second law and applications

An ice cube is placed on a table and begins to melt.  The following conclusion can be made.

• Energy is being absorbed by the table which causes the cube to melt.
• Energy is being transferred from the table to the ice cube.
• Energy is being created by the air and table and making the cube heat up.
• Energy  is being created by the ice cube and is being released to the air
