What’s The Hottest Hot and Coldest Cold?

The hottest hot and coldest cold are the extremes we can feel on Earth, like touching fire or ice.

Imagine holding a candle flame in your hand. That’s pretty hot! But the hottest hot is like being right next to a volcano that's erupting, super, super hot. In fact, scientists say the hottest hot on Earth is around 70 degrees Celsius (which is like 158 degrees Fahrenheit). That’s hotter than a boiling kettle!

Now think about the coldest day you’ve ever had, your breath turns into smoke, and your nose feels frozen. But the coldest cold is way colder than that. It's like being inside a freezer for hours and then stepping outside into snowflakes that are tiny ice cubes. The coldest cold on Earth is around -90 degrees Celsius (which is like -130 degrees Fahrenheit). That’s so cold, it could freeze your toes in seconds!

So the hottest hot makes you sweat, and the coldest cold makes you shiver, both are amazing extremes we can feel every day.
