AnswersAnswers
  1. It's the Atacama desert in Chile, according to the National Geographic. Although some do argue that it is Antartica.
  2. It's Severn Trent Water, with eight million customers across Wales, the Midlands and Yorkshire. Chef Tom Aikens, who was on the judging panel, described it as having a "clear taste" and being "very fresh".
  3. It is 68C. Water's boiling temperature is related to the barometric pressure, so at sea level it is 100C but at the top of Everest - 8,848m up - it's 68C.
  4. False - it's blue. Although in small amounts water looks clear, it is in fact a light blue colour.
  5. It's 2.5%, according to the Univeristy of Michigan. The rest is mostly undrinkable saltwater in oceans and seas.
  6. It is D2O - heavy water is so-called because it has a higher proportion than normal of the isotope deuterium.
  7. It's 15%, according to Ofwat, the water industry regulator.
  8. It's 1.6in. The average monthly rainfall in Sussex is 2.2in (5.7cm).
  9. It's Scotland. Loch Morar in the Highlands has a maximum depth of 310m.
  10. It's 10 times, according to the Met Office. In parts of the western Highlands, the average annual rainfall is about 200in (500cm) and in the driest parts - East Anglia and the Thames Estuary - it's about 20in (50cm).
