Consider the following statements:

1. At night, sea water cools down more slowly than land and cool air from the land moves towards the sea. This is called the night breeze.
2. If two identical spheres of the same radius R, out of which one is hollow containing air and the other is solid are heated at the same temparature, the change in dimensions of the spheres will be same in both the spheres.

Which of the given statements is/are correct?

Statement (1) is incorrect. At night the sea water cools down more slowly than the land and the cool air from the land moves towards the sea. This is called the land breeze, not night breeze. Statement (2) is incorrect. Air being a bad conductor of heat compared to the metallic sphere which is a good conductor, the maximum heat is utilized in expanding the metallic part. In case of solid, the change in radius will be greater due to the metallic substance present in it.
