which is a type of heat transfer that causes the air at the top floor of a building to be hotter than the air at the bottom floor of a building?\nconduction\nconvection\nradiation\nreflection
Answer
Brief Explanations:
Convection is the transfer of heat by the movement of a fluid (in this case, air). Warmer air is less dense and rises, while cooler air is denser and sinks. In a building, this natural - convection process causes warmer air to accumulate at the top floor. Conduction is heat transfer through direct contact, radiation is heat transfer through electromagnetic waves, and reflection is not a heat - transfer method related to this phenomenon.
Answer:
B. convection
