Deep under your feet lie countless rivers, lakes, and seas of liquid methane.

Remember those seas of liquid methane?

This gas reacts with the lubricating liquid in our eyes and produces sulfuric acid, which makes us cry.

During sublimation, a solid on heating, converts directly into vapor without passing through the intermediate liquid state.

Now, in order to wash off this acid, our lacrimal glands produce a disinfecting liquid.

But when our eyes cannot hold any extra amount of disinfecting liquid.

When you're microwaving a liquid, you don't need to reduce the power because heat transfers through liquids much more efficiently than it does through solids.

This direct transfer of heat is the basic idea behind the radiators in car engines, liquid cooling of fancy gaming computers, and water cooling of power plants.

A liter of water can move 1 calorie of heat per degree Celsius it heats up, so using water for liquid cooling can remove at most around 37 Calories of heat every hour

So we start collecting this liquid coming out.

We call it saliva, but it's the liquid coming out of the mouth.

However, the sea being a liquid, forms a smooth surface.

Without passing through the intermediate liquid state.
