Answer 1

Answer:

$\Large \boxed{\mathrm{convection}}$

Explanation:

When the candle is burning, the air around it gets heated.

The hot air is less dense and lighter than normal air, so the hot air rises. Air that is less dense rises upward.

The hot air that rises, spins the spiral paper.

The movement occurs due to convection.

Convection is heat transfer through liquids and gases.

Answer 2

Your question has been heard loud and clear.

Well , movement of paper is due to air. This air has risen from below to the level of the paper to cause movement in it. Air that is hot , rises from below to above because hot air is light. This air is hot air.

If it was radiation , there would be no air. The paper would simply heat up.

It cant be conduction bc , conduction needs a medium to pass the heat to the paper.

It definetly is not evaporation , evaporation doesnt cause winds , only water vapour , and if it was evaporation , the paper would be wet from moist air but it isnt.

The answer is convection. Yes , it is convection bc it generates hot and cool air from production of heat by any substance , it caused hot air here , which caused movement of paper.

Thank you
