The correct statement is: Heat is transferred from the metal block to the ice cube, and the ice melts.
The correct statement is "Heat is transferred from the metal block to the ice cube, and the ice melts."
When the ice cube is placed on the metal block, heat is transferred from the higher temperature metal block to the lower temperature ice cube. This process is known as heat conduction. The metal block has a higher thermal energy than the ice cube, so it transfers heat to the ice cube. As a result, the ice cube absorbs the heat energy and begins to melt.
