Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Ice in the shikanji
Where the chapter begins.
Thirav thought ice and water must be different substances, because ice can be held in your hands.
Water on a steel plate
The activity that settles it.
One tablespoonful on a steel plate goes, and nothing shows up underneath.
Condensation
The word to learn.
Water vapour turning into its liquid state is the process called condensation.
A cold surface
What it needs.
Vapour in the air meets a cold surface and comes out of it as water droplets.
Cold water and ice cubes
The activity.
Leave a tumbler of cold water with a few ice cubes undisturbed for five minutes.

1
Water That Disappears
A spoonful of water on a steel plate goes, and none of it comes out underneath. That is enough to show where it went: into the air as vapour, by the process we call evaporation.
- Ice and water are two forms of one substance, and such forms are also called states.
- Water flows and splashes, while ice does neither.
- A spoonful of water on a steel plate vanishes without any of it reaching the other side.

Droplets on a Cold Glass
Drops appear outside a tumbler of iced water. A weighing balance and a marked water level together show that they did not leak out, and name where they came from: the vapour in the air, condensing.
- Cold water and ice cubes in a tumbler bring water droplets to its outer surface.
- Small droplets are deposited first, and they combine together to form bigger drops.
- Thirav suspected the water had seeped out, but the level inside had not gone down.

Three States, and How to Switch Them
Ice keeps its shape, water takes the shape of its container, and vapour fills all the space there is. Heating and cooling move a substance from one of those states to another.
- Water is met in three states in daily life: ice, liquid water and water vapour.
- Ice holds on to its own shape whatever container it is put in, and it neither flows nor spreads.
- Water flows, has no fixed shape, and takes the shape of its container.

Faster, Slower, and Why a Matka Cools
Spread water out, warm it, or blow air across it and it goes sooner; damp air holds it back. And water leaving a surface takes warmth with it, which is the whole secret of an earthen pot.
- Water spread out on a plate has a larger exposed area, so it evaporates faster.
- A fair test changes one condition, keeps the rest the same, and measures the time taken.
- Water in a bottle cap kept in sunlight evaporates faster than one kept in shade.

Clouds, Rain and the Water Cycle
Vapour rises, cools, and gathers into droplets around specks of dust. Those droplets make clouds, join into heavy drops, and fall as rain, closing a circulation called the water cycle.
- Water vapour is lighter than air, which is why it rises into the atmosphere.
- Air moving higher above the Earth's surface becomes cooler and cooler.
- High enough up, the vapour comes out as droplets, generally built around specks of dust.
