Physics Planets do not twinkle because

They are nearer to earth and hence we receive a greater amount of light.
Their distance from the earth does not change with time
They are very far away from the earth resulting in decrease in intensity of light
They emit light of a constant intensity

Physics At hill stations, the boiling point of water will be

Same as at sea level
More than that at sea level
Less than that at sea level
Equal to the melting point of ice

2 metres
