Where will it take more time to cook rice?
It will take more time to cook rice on Mount Everest due to the lower atmospheric pressure at high altitudes, which lowers the boiling point of water. This means water boils at a temperature below 100°C, slowing the cooking process.

Cooking rice takes longer at higher altitudes because the atmospheric pressure is lower, which reduces the boiling point of water. On Mount Everest, the boiling point of water drops significantly below 100°C due to the extremely low atmospheric pressure. This lower boiling temperature means that the water is not as hot as it would be at sea level, resulting in slower cooking times.
Among the given options:
– [A] On the sea coast, the atmospheric pressure is normal, and water boils at 100°C, making cooking times standard.
– [B] At the depth of the sea, pressure increases, raising the boiling point of water, but cooking there is impractical.
– [C] In Shimla, at a moderate altitude, the boiling point is lower than at sea level but higher than on Mount Everest.
– [D] On Mount Everest, the boiling point is the lowest, significantly increasing cooking time.
Therefore, the correct answer is [D] On Mount Everest.
