SPM Physics: AHA! Melting Ice – Latent Heat of Fusion

 


Why does melting ice cool your drink?

  • The temperature of the drink is higher than the ice.

  • Heat flows from the warmer water to the colder ice.

  • Heat is used to weaken intermolecular bonds.

  • Ice changes from solid to liquid.

  • The drink loses heat, so its temperature decreases.

The physics concept involved is latent heat of fusion. Cooling happens because heat is absorbed during melting, not because the ice is “cold.”

Exam tip: For full marks, write the complete chain: heat flows → bonds weaken → ice melts → heat removed → drink cools.

AHA! Ice absorbs heat, drink feels cool. Not by sight, but by INSIGHT!
