Why do flames burn upwards?
In a gravitational field, flames usually burn upwards because the hot gases in the flames are less dense than the surrounding gases, hence buoyant forces cause the hot, luminous gases (which we see as the flame) to rise. In a zero gravity environment, the direction of the flame is not necessarily "up" since "up" is arbitrary without a gravitational field.
How flame propagate?
Flame propagation refers to the spread of flames through a combustible material or gas mixture. It occurs when a heat source ignites the fuel, producing hot gases that rise and create convection currents, which in turn can ignite nearby fuel. The flame spreads as the heat from the combustion process heats adjacent fuel, leading to further ignition. Factors influencing flame propagation include the type of fuel, concentration, temperature, and environmental conditions such as wind and pressure.
What happens to the molecules in a sovelent when it heats up?
They speed up and moves faster and faster.
Does aluminum heats up faster than copper?
No, copper heats up faster than aluminum because copper has higher thermal conductivity. This means it can transfer heat more efficiently leading to faster heating.
Why a flame always points upwards?
The combustion reaction heats the air, causing the air molecules to vibrate faster and move further apart. This means that the gas in the flame expands and becomes less dense than the air around it, causing it to rise.
Flames of a fire rise even though gravity pulls things downwards?
The air above and around the flame heats up, expands and moves up. Cooler air below the flame moves in to take its place, heats up, rises and the process repeats itself.
On a Bunsen burner which flame produces a sooty carbon black deposit on whatever it heats?
A yellow, sooty flame produced by a Bunsen burner is known as a reducing flame. This flame has incomplete combustion due to a lack of oxygen, leading to the formation of carbon particles that deposit as soot on whatever is being heated. Adjusting the air inlet on the burner can help achieve a cleaner, blue flame for more efficient heating.
Which heats up faster by day?
The desert heats up faster.
What heats a burner flame?
gas
Do different colors of fire have different heats?
Ofcourse, Yellow Flame - Matches or Lighters (butane) (The Coolest, still dont try touching it though) Orange Flame - Coal or Wood Red Flame - Indian Ink Blue Flame - Natural Gas Clear Flame - Hydrogen (The Hottest)
What is the purpose of the flame that is lit below a hot air balloon?
To increase enthalpy.the burner uses flames to heat the air so the balloon will rise
Why does flames of acandle rises upward?
The flame of a candle rises upward due to the convection currents created by the heat from the flame. As the flame burns, it heats the surrounding air, causing it to become less dense and rise. This creates a continuous flow of hot air moving upward, carrying the flame along with it.
Why do flames burn upwards?

What manipulated variable that heats up faster water or soil?
the water heats faster than soil.
Why flame on a candle burns erect?
The flame heats the air and it is lighter so it goes upwards.
What heats up inside a kettle?
Water heats up inside a kettle when it is placed on the stove or plugged into an electrical outlet. The heat source, whether it be gas flames or an electric heating element, transfers energy to the water molecules, causing them to move faster and increase in temperature.
How many squire feets does the MHVFB10LP propane blue flame heats?
Heats up to 300 sq ft
