Ice sits on a metal block and begins to melt.

Choose the TRUE statement below about this situation.

• The metal is TRANSFERRING thermal energy to the Ice.

• The ice is TRANSFERRING thermal energy to the block.

• The ice is TRANSFORMING the metal's energy into thermal energy.

• No energy is being transferred or transformed.

• The ice is DESTROYING the metal's energy, allowing it to melt.
