multiple - choice question\nhot air will __________ and expand. (select 1)\ncondense\nsink\nrise\nnot move
Answer
Brief Explanations:
Hot air is less dense than cold air. According to the principle of buoyancy, less - dense substances rise in more - dense substances. Condensing is related to cooling and changing from gas to liquid, sinking is for denser substances, and 'not move' is incorrect as air has movement due to temperature differences.
Answer:
C. rise
