What is Newton’s law of cooling?

Newton’s law of cooling is about how hot things cool down over time when they’re in a cooler environment.

Imagine you have a hot cup of chocolate milk, and you leave it on the table. The room is cooler than the milk, so the milk starts to lose its heat, just like your hands get warmer when you hold a hot mug, but also cool down if you let go of it for a while.

When something is hot and surrounded by something cooler, it loses heat at a certain speed. The bigger the difference in temperature between the hot thing and its surroundings, the faster it cools down. But as time goes on, that difference gets smaller, like when you take a shower and the water starts to feel less warm.

Think about a hot pizza coming out of the oven. At first, it’s super hot, so it quickly loses heat. After a few minutes, it's still warm, but not as fast as before, just like how your soup gets cooler in your bowl over time.

So, Newton’s law of cooling is like watching something go from “super hot” to “just right,” step by step! 🍕☕
