Question

why does an ice cube melt when you hold it in your hand?
the ice cube radiates heat to your hand.
heat from the ice cube is transferred to your hand.
heat is transferred from your hand to the ice cube.
your hand transfers temperature to the ice cube.

Explanation:

To determine why an ice cube melts in your hand, we analyze heat transfer:

• Ice has a lower temperature than the hand. Heat flows from higher - temperature objects (hand) to lower - temperature objects (ice cube) due to the temperature difference.
• Option 1: Ice is colder, so it can't radiate heat to the warmer hand.
• Option 2: Heat doesn't flow from the colder ice to the warmer hand.
• Option 3: This is correct. The hand is warmer, so heat is transferred from the hand to the ice, providing the energy needed for the ice to melt (changing from solid to liquid).
• Option 4: Temperature is a measure of heat intensity, and it's not transferred. Heat (energy) is transferred.

Answer:

C. Heat is transferred from your hand to the ice cube.
