A student observes that when they leave a cold drink on the table, it eventually becomes warm. What principle does this observation illustrate?

• The drink absorbs heat energy from the table due to convection.
• The drink absorbs cold energy from the air due to conduction.
• Cold naturally flows from the drink to the surroundings due to the First Law of Thermodynamics.
• Heat naturally flows from the warmer surroundings to the cooler drink due to the Second Law of Thermodynamics.
• Cold naturally flows from the drink to the surroundings due to the Second Law of Thermodynamics.
