Correspondence between Chemical and Physical Phenomena and their Examples

To establish the correspondence between chemical (1) and physical (2) phenomena and their examples, let's analyze each phenomenon and its corresponding examples:

1. Yellowing of leaves (Пожовтіння листя): This is a chemical phenomenon that occurs due to the breakdown of chlorophyll in the leaves, leading to a change in color. The yellowing of leaves is often associated with aging or nutrient deficiencies in plants [[1]].

2. Crushing of chalk (Подрібнення крейди): This is a physical phenomenon that involves breaking down a solid material into smaller pieces without changing its chemical composition. When chalk is crushed, it breaks into smaller fragments while retaining its chemical properties [[2]].

3. Uncoiling of a metal spring (Розкручування металевої пружини): This is a physical phenomenon that occurs when a coiled metal spring is stretched or unwound. The uncoiling of a metal spring is a result of the physical forces acting on the spring, without any chemical changes taking place [[3]].

4. Fermentation of grape juice (Бродіння виноградного соку): This is a chemical phenomenon that involves the conversion of sugars in grape juice into alcohol and carbon dioxide by the action of yeast. Fermentation is a chemical process that occurs under specific conditions, such as the presence of yeast and absence of oxygen [[4]].

Based on the given options, the correspondence between the chemical (1) and physical (2) phenomena and their examples would be:

1. Yellowing of leaves (Пожовтіння листя): 1A 2. Crushing of chalk (Подрібнення крейди): 2В 3. Uncoiling of a metal spring (Розкручування металевої пружини): 2Г 4. Fermentation of grape juice (Бродіння виноградного соку): 1Б, 2А
