At the boiling point, water turns into vapour inside the liquid itself, and these pockets of steam are the bubbles that rise and burst at the surface.

Light travels fastest in vacuum and almost as fast in air, so in any material medium it moves more slowly than in air, and the ratio of the two speeds is greater than one.

Power is the reciprocal of focal length in metres, and 50 cm is 0.5 m, so the power is 1 divided by 0.5, which is +2 dioptre.

When salt crystals grow inside the pores and cracks of a rock, they push the grains apart and break the rock mechanically, without changing its minerals.

Basavanna did lead the Virashaiva movement, but the Virashaivas encouraged post-puberty marriage and widow remarriage precisely because the Dharmashastras disapproved of them.

The Irrigation Commission of 1972 treated an area as drought-prone when less than 30 per cent of its gross cropped area was irrigated, so an area with 30 per cent or more is left out.

Ashoka's dhamma was a moral code for all his subjects and never asked people to honour or worship the king himself.

In the light reaction of photosynthesis, water is broken up; its hydrogen is used to make food and its oxygen is given out.

A cloudburst is very heavy rain over a small area in a short time, and in India it mostly strikes in the monsoon, setting off flash floods and landslides.

Sulphur vapour turns straight into solid sulphur on the cooler rocks without first becoming a liquid, and a direct change from gas to solid is called deposition.

Almost all the world's ammonia is made by combining nitrogen and hydrogen directly in this process. In the Haber-Bosch process, nitrogen from the air and hydrogen, usually obtained from natural gas, are made to react in the ratio 1 to 3.

All three statements follow from how the Coriolis force turns winds around low and high pressure. A cyclone is a low-pressure centre into which winds blow, and an anticyclone is a high-pressure centre from which winds blow out.

Nitrogen has five electrons in its outer shell and needs three more to complete an octet, so its valency is 3.

Condensation depends on how much air there is, how much moisture it holds and how cold it becomes, so all three factors count.

Breaking lead nitrate into lead oxide, nitrogen dioxide and oxygen needs a steady supply of heat, so the reaction absorbs energy and is endothermic.

Extratropical cyclones form outside the tropics and cover wide areas, but they travel from west to east, not east to west.

All three statements correctly describe slash-and-burn farming in India. Slash-and-burn is a form of primitive subsistence farming: farmers clear a patch of forest by cutting and burning the vegetation, grow food crops on it with simple tools, and mainly feed their own families.
