Study the given experimental arrangement and answer the given questions.
The arrangement shows two identical paper cups suspended from the ends of a horizontal wooden stick. A burning candle is placed below one of the cups. After heating, the cup above the candle moves upward because the heated air rises.
1. The wooden stick is initially horizontal. After the candle is lit, the side containing the heated cup rises.
