We smell because of particles in the air. Air currents , due to people moving about or fans in the room. carry the particles across the room and the nerves in your nose detect them.
The molecules of perfume are in a gaseous state and mixing with the molecules of air in the room. All of them undergo random motion at all times as a result of the internal ("heat") energy that they have absorbed.
the rate at which a smell diffuses across a room depends on the mass of the particles and the density of the substance. If a substance has a low density it will diffuse faster and also if it has a low mass it will diffuse faster.
Running or sprinting would be the fastest way to get across a room.
At room temperature, acetic acid (CH3COOH) is a liquid. It is a colorless liquid with a characteristic pungent smell and is commonly known as vinegar in diluted form. When cooled to low temperatures, it can solidify into a crystalline form.

You can smell a burning candle across a room because the heat helps disperse the scent molecules into the air, allowing them to travel further. This process, called diffusion, enables the scent to reach your nose even from a distance.
You can smell a burning scented candle across the room due to the molecules released from the candle vaporizing and dispersing through the air. These molecules enter your nose and stimulate your olfactory senses, allowing you to detect the scent even from a distance.

You could say the room has a moist smell.Another way would be: This room has a musty smell.
you pu t dinner on the table and you can smell it all the way across the room
Nasty smells spread across a room because the particles carrying the odor become airborne and are carried by air currents. These particles can travel and disperse throughout the room, making the smell more noticeable. Open windows or ventilation can help disperse the smell quicker.
No. Vapour does not smell.
the liquid vaporizes and the resulting gas molecules wander about the room
the gas in the room freshener mixes with the air in the room and as air moves , the smell from the room freshener spreads through out the room
The gaseous state of matter is responsible for you smelling the perfume of someone across the room. The perfume molecules evaporate into the air as gas particles and travel through the air to reach your nose. This is how you are able to smell the perfume from a distance.
the rate at which a smell diffuses across a room depends on the mass of the particles and the density of the substance. If a substance has a low density it will diffuse faster and also if it has a low mass it will diffuse faster.
