none of the above

Answer 1

2. December 21

3. They move faster.

Step-by-step explanation:

2. The midnight sun or polar day is a natural phenomenon observable in the north of the Arctic Circle and south of the Antarctic Circle, consisting of that, on dates close to the summer solstice, the Sun is visible 24 hours a day.

3. The energy makes the air particles move faster, they collide with others that are at a lower temperature, that move more slowly. As they collide, fast particles yield some of their energy to slower ones. These in turn collide with other adjacent particles. This process continues until the energy is extended to all the particles of the air that was initially at a lower temperature. Finally they all reach the same kinetic energy and consequently the same temperature.

Answer 2

The Antarctic Circle has 24 hours of daylight around the summer solstice. In the southern hemisphere this would be around December 21.

When energy is transferred to air the particles of air move faster. Adding energy to molecules makes them move faster and air is no exception.
