Final answer:
Leaving the freezer door open causing ice to melt is an endothermic reaction transferring energy to the ice cube.
Explanation:
An endothermic process is when energy is transferred from the surroundings to the ice cube, causing it to melt. In this scenario, leaving the freezer door open caused the ice to melt due to the absorption of energy from the room, making it an endothermic reaction.
Exothermic reactions involve the release of heat into the surroundings, like when ice forms in the freezer and heat is pulled out of the water. This contrasts with the endothermic process of ice melting from absorbing heat.
Melting ice in the open freezer is an example of an endothermic reaction as the ice absorbs heat from the surroundings, causing it to change from a solid to a liquid state.
