Atoms and molecules need energy (such as HEAT) in order to move around and change from solid to liquid to gas.

created by condensation

Misty Breath by Celia Berrell When morning air is very cold our breath can make a misty cloud. The water vapour from our lungs condenses where cold air’s around. Water warmed by blood-hot lungs is energised as water gas but quickly turns to liquid form when cooled by air or things like glass. So breathing on a mirror will create some moist and misty spots as water vapour turns to drops of tiny liquid water dots. In colder climes in olden times if you were ill and looked like death they’d place a little mirror by your open mouth … to check for breath.

Life-Friendly Water Facts

• Water covers 70% of Earth’s surface • 96.5% is in the salty seas • 3.2% is underground or in glaciers • Less than 1% is available as fresh

water

• A baby is 75% water • A potato is 79% water • A banana is 74% water • An old person is less

than 60% water

Camel Calamity by Celia Berrell There’s lots of desert area throughout outback Australia. It rarely rains, but water’s found in tables hiding underground. The settlements and tiny towns have had to dig a long way down installing pumps to push it up to give them water from a tap. Of all the animals nearby there’s one that copes well in the dry. A camel can last two whole weeks before a water source it seeks. And recently they’ve learnt a trick that helps them get a big long drink. By walking into some small town and turning on the taps they’ve found.

This causes a calamity as precious water’s running free. A camel isn’t smart enough to know those taps need turning off!

dew © Celia Berrell 2017 part 2

A recent rain to quench and share. A cloudless night to cool the air. The slightest breeze to chill on cue the grass and leaves. Here comes the dew. The stage is set for dawn’s sensation. Jewel-studded condensation. Blanket-strewn on grassy stems are rainbow-sparkling water gems.

SHAPE ME A RAINDROP

Depending on the temperatures and air pressures in a raincloud, the falling water could be liquid or solid. What shape do you think a liquid raindrop is? Well, they’re not pointed at the top like a teardrop shape! The smallest raindrops are spherical, like a blueberry. Slightly bigger drops are shaped like the top-half of a burger bun. Bigger still, and a raindrop will spread out like a pancake as it falls through the air. If raindrops get too big, they will break up into two or more smaller droplets again. But before they do, some of them make the shape of a parachute.

Blueberry Pancakes & Parachutes by Celia Berrell Shimmering streaks of morning-time rain puddling into the mud. reminds me of blueberry pancakes and circular see-through parachutes. Raindrops aren’t teardrops. There’s no pointy tip. Those free-falling globules are blueberry round. But if they meet up as they fall through the sky a middle-sized raindrop as-flat-as-a-pancake might suddenly start to appear.

Blueberry Pancakes & Parachutes by Celia Berrell (continued) Bigger and larger and bulkier still fast-falling raindrops past-pancake-proportions will stretch in the centre and drag through the air.

For less than a second becoming a dome these small glassy parachutes wobble then burst to break into blueberry droplets again.
