* Heat is energy: Heat is a form of energy that causes molecules to move faster.
* Temperature is a measure of heat: The higher the temperature, the faster the molecules are moving.
* Heat always flows from hot to cold: When a hot object comes into contact with a cold object, heat energy will flow from the hot object to the cold object until they reach the same temperature.
Here's how it works with ice:
1. Ice is cold: Ice is at a lower temperature than most things it comes into contact with. This means its molecules are moving slower.
2. Heat transfer: When ice touches something warmer, like your hand or a drink, heat energy flows from the warmer object to the ice.
3. Melting: This heat energy causes the ice molecules to vibrate faster, which breaks the bonds holding them in a solid state, causing the ice to melt into liquid water.
4. Cooling: As the ice absorbs heat, the other object loses heat, which is why it feels cold.
In short: Ice doesn't transfer coldness. It absorbs heat energy, causing itself to melt and the other object to cool down.
