When you add cold milk and hot chocolate, they will slowly blend as the cooler liquid mixes with the warmer liquid. Eventually, the heat will be spread out Ovenly through the entire liquid. Which statement best explains why this happens? (1 point) Heat always moves from areas of higher temperature to areas of lower temperature. The liquids attract each other because the densities of the liquids are the same. Cold liquids rise and hot liquids sink making the liquids mix. The molecules of the two liquids form chemical bonds to spread energy.

Heat always moves from areas of higher temperature to areas of lower temperature. This phenomenon is known as thermal conduction. When you introduce cold milk into hot chocolate, the heat energy from the hot chocolate transfers to the cooler milk until both reach an equilibrium temperature. It's a delightful dance of molecules as they work to achieve that silky smooth blend! In real-world applications, this principle is why you often notice how a hot cup of coffee gradually cools down when you add cold cream or milk. It’s not just your taste buds enjoying the mix; it’s basic thermodynamics at play! This concept can also be seen in cooking, where adding cold ingredients to a hot pan can lower the overall temperature of the dish, altering the cooking process and affecting the final flavor and texture. Enjoy your cozy cup!
