Fire is a combination of heat and light energy emitted by a chemical reaction, and as such it has no mass and therefore no density.

How does Canada's population density compare to the rest of the world?

Canada's population density is quite dense. The density is densely condensed into one densely dense country. The population density is dense enough to form a flaming ball of people if a single fart is lit on fire. and on a whole other note, yes, it is possible to light farts on fire. But back onto density. Ah yes, density, how dense can the population get? well if you squished the whole population of Canada together and rolled them all up into one big dense ball, it would be half the size of 'mericas dense ball. Then we would have some foreign dude come and light them in a blaze and the fire that gets the biggest, that country will have the smallest population density. you are welcome :)

Why will water not extinguish a hydrocarbon fire?

Most hydrocarbons are less dense than water. So, if you put water on a hydrocarbon fire, they will simply float on top of it, rending the water ineffective.


Which kind of heat transfer causes smoke to rise from a fire?

Convection is the heat transfer process responsible for causing smoke to rise from a fire. As air near the fire gets heated, it becomes less dense and rises, carrying the smoke along with it.


Why does the Hot air balloon rise when the fire is lit beneath the balloon?

The fire warms up the air and the air becomes less dense. So the balloon traps the warm air and since less dense gases rise with denser gasses around it, the warm air rises taking the balloon with it.


Why fire moves up in direction?

Fire moves upward due to the natural convection process. As the fire heats the surrounding air, it becomes less dense and rises, creating a flow of air upwards. This convection current carries the flames and heat upwards, which is why fire tends to move in an upward direction.


Flames of fire rise even though gravity pulls things downwards?

Yes. Fire goes upward precisely because Earth's gravity pulls things downward. The fire is lighter (less dense) than the air that replaces it, so the air pushes the hot air from the fire upwards.


What are the best fire bricks for a fire pit?

The best fire bricks for a fire pit are typically made of dense and heat-resistant materials like clay or refractory concrete. These bricks can withstand high temperatures and help retain heat efficiently in the fire pit. It's important to choose bricks specifically designed for use in fire pits to ensure safety and durability.
