What is cooler?

"What is cooler?" is like asking which ice cube will melt faster, one that’s big and heavy or one that's tiny and light.

Cooler means something has less heat, so it can make other things feel colder. Think about your favorite drink on a hot day, if you put an ice cube in it, the drink gets cooler because the ice takes away the heat.

Now imagine two ice cubes: one is like a big block of ice that’s been sitting outside all day, and the other is a small, fresh ice cube from the freezer. The smaller ice cube is cooler because it started off colder and hasn’t had time to warm up yet.

If you put both in your drink, the smaller one will make your drink feel cooler faster, just like how a tiny snowball can melt quicker than a big snowman on a sunny day.

So when we ask "What is cooler?", we're really asking: Which thing has more cold power to take away heat from something else?"What is cooler?" is like asking which ice cube will melt faster, one that’s big and heavy or one that's tiny and light.
