You can smell a burning scented candle across a room because the scent molecules in the candle are released into the air and travel through the air. These molecules can travel further than the heat and light of the candle, allowing the scent to be detected from farther away.
Temperature of the wax – the higher the temperature of the wax, the more energy you give the oil molecules to collide with each other and evaporate into the air, where they diffuse through the air in your kitchen and eventually to your nose.
