Luca sees snow melting from a roof as the sun comes out. Later he notices that the melting snow froze into icicles during the cold
night. How is energy related to these changes of state?
Thermal energy affects the difference in freezing points.
Thermal energy is absorbed during melting, and then is released as it
freezes.
O The amount of thermal energy absorbed is affected by low melting
points.
Thermal energy flows from cold objects to hot objects as they freeze.
