Question 9 (1 point) Which type of changes are melting, freezing, and boiling? nuclear compound chemical

Melting, freezing, and boiling are all fascinating examples of physical changes, where matter alters its state without changing its chemical composition. For instance, when ice melts into water, the molecules are simply moving from a solid arrangement to a liquid state, while the chemical structure of H2O remains the same. It’s like a dance party for molecules, where they get to switch up their moves but keep their identities! In real-world applications, understanding these changes is essential in everyday life—think cooking! When you boil water for pasta, you're not altering the water's chemical makeup, but you're taking advantage of that physical change to cook your food. Similarly, when you freeze fruits for smoothies, you're ensuring they keep their deliciousness while just temporarily changing their state. Who knew science could make us such fabulous chefs?
