Question

why do candle flame rises upwards​

Answer 1

$\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}⋆$

A candle flame keeps pointing up because it heats the surrounding air, creating streaming currents around itself. Warmer air is thinner and lighter than cooler air, since gas molecules spread out when they gain energy. As the heated air near a flame expands, it also rises, since it's lighter than the air around it.
