measures how many (usually) parts per million (ppm) of whatever smoke/gas/etc is being looked for. For instance a smoke detector looks for X ppm of smoke in air, or a CO2 sensor measures the ppm of CO2 in air - ppm is a measure of density.
To find the density of smoke, you would need to measure the mass and volume of a sample of the smoke. Divide the mass of the smoke by its volume to calculate the density. Keep in mind that smoke is a complex mixture of particles and gases, so its density can vary.

Smoke travels upward due to differences in temperature and density between the smoke particles and the surrounding air. As the smoke is hotter and less dense than the surrounding air, it rises. This movement is also influenced by the natural convection process, where the hotter air at the bottom of the smoke column rises as it cools and disperses at the top.
flammability density smoke burned
Because it's density is greater than that of atmospheric/ambient air, duh....,
Smoke rises in the air due to the difference in temperature between the smoke and the surrounding air. When materials are burned, the heat causes the air inside the smoke to expand, making it less dense and causing it to rise. This process creates air currents that carry the smoke upwards.
Smoke and hot gases tend to go upwards.
Yes, long-wave infrared will penetrate even very dense smoke. That's why thermal imagers are effective in firefighting. For instance, you can feel the heat (infrared spectrum) through smoke, but you cannot usually see through smoke (visible spectrum).
On a hot day, the density of the air will be less than that of the cold day since the low presence of moisture/ suspended water particles. Smoke is a stream of suspended partcles having sizes in a very few microns. When they get discharged into air in a hot day, due to low density of air at that time they try to flyaway.
In this simile from "To Kill a Mockingbird," smoke and fog are being compared to emphasize the abundance and density of smoke emanating from the house. The simile creates a vivid image of the smoke's volume and movement, likening it to the way fog rolls off a river bank.
Smoke machines work by heating a special fluid, usually a glycol-based solution, to create vapor. This vapor is then released into the air, where it cools and condenses to form a visible mist or fog. The machine can control the density and volume of the smoke, allowing for different effects like haze or thick clouds. This smoke enhances lighting effects and creates a dramatic atmosphere for performances and events.
Americium-241 is commonly used in smoke detectors for detecting smoke particles. It is also used in certain types of industrial gauges for measuring thickness and density of materials. Additionally, it has applications in oil well logging tools for exploring and accessing oil reserves.
