A fridge is like a mini weather machine. When it’s cold inside, that’s because something called ice magic happens, you can’t see it, but it makes everything freeze! It uses a special gas that turns from liquid to vapor and back again, taking heat away. Just like when you blow on your hand to cool it down, the fridge does the same thing, but with invisible gases.
Examples
- The fridge takes heat from your soup and dumps it outside, keeping your fridge cold.
