What are cooling processes?

Cooling processes are ways things get colder, just like how ice cream melts but also gets colder when you put it in the freezer.

Imagine you have a hot cup of cocoa on a cold day. If you leave it out, it slowly becomes cool, that’s one kind of cooling process. But if you put it in the fridge or freezer, it gets cold much faster, that's another kind!

• When something is hot, its particles are moving fast, like kids running around at playtime.
• When they slow down, the thing becomes cooler, just like when the kids sit down to rest.

Some things cool down slowly, like a warm blanket on a chilly night. Others cool down quickly, like when you take a hot shower and then turn off the water, whoosh, it gets cold in no time!

Cooling processes are all about how fast or slow something changes from hot to cold, just like how different foods take different times to cook!
