When ice cubes melt in a glass of water, a current forms in which heat energy moves from particles with a higher temperature to particles with a ___________ temperature.

Materials such as metal and wire are good ___________ because heat can easily transfer through them.

Thermal energy moves from objects with

• higher temperatures to objects with lower temperatures

• lower temperatures to objects with higher temperatures

Insulators __________ thermal energy transfer

• maximize

• minimize
