A candle flame points upward when placed horizontally due to the convection currents created by the heat of the flame. The heat causes the surrounding air to warm up and rise, creating a flow of air that pulls the flame upward. Additionally, the flame itself is composed of hot gases that are less dense than the cooler air around them, further contributing to the upward movement. This phenomenon demonstrates the principles of buoyancy and convection in fluid dynamics.
What else can I help you with?
Is candle flame a source of light?
The flame of a candle is a source of light.
If a plant and a burning candle are placed under a bell jar will the candle burn?
No, the candle will not burn because the flame will consume the oxygen inside the bell jar, creating a vacuum and extinguishing the flame. Oxygen is necessary for combustion to occur, and without it, the candle cannot burn.
When a glass jar is placed over a lighted candle why the flame goes off?
When a glass jar is placed over a lighted candle, the flame eventually goes out due to a lack of oxygen. The candle burns oxygen to sustain the flame, and as the jar seals it off, the available oxygen inside the jar is consumed. Without sufficient oxygen, the combustion process cannot continue, leading to the extinguishing of the flame. Additionally, the heat from the flame warms the air inside the jar, causing it to expand and create a slight vacuum, further limiting oxygen supply.
Why is it hotter if you put your hand above a lighted candle than at the sides if the candle's flame?
When you place your hand above the lighted candle, you are closer to the source of heat, which is the flame. The heat rises vertically from the flame and directly impacts your hand when placed above it. On the other hand, when your hand is at the sides of the candle, you are farther away from the direct source of heat, so you feel less heat.
Is candle wax flammable?
Yes, candle wax is flammable. When a candle is lit, the heat from the flame melts the wax, which is then drawn up the wick and burned to create the flame.
Why flame of candle will go upward?
gravitational force con't effect on gasses..
What is a sentence using the word flame?
The flame of the candle was placed too close to the centerpiece.
Why does the candle flame goes out when placing a glass over it?
When a glass is placed over a candle flame, it acts as a barrier by cutting off the oxygen supply needed for combustion. Without oxygen, the candle cannot sustain the chemical reaction that produces the flame, causing it to go out.
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 does a candle go out when burning in a sealed jar?
A candle requires oxygen to burn, and when placed in a sealed jar, the oxygen supply is depleted, leading to the candle extinguishing. This happens because the flame consumes the available oxygen, creating a vacuum that eventually snuffs out the flame.
What happens to a candle in a spacecraft?
In a spacecraft, a candle flame burns in a more rounded shape due to lack of gravity pulling the flame upward. The lack of convection causes the flame's heat to be trapped near the candle, making it burn more slowly and with less flickering. Additionally, the candle produces more soot in microgravity as combustion is less efficient.
If you lift the glass tumbler which is placed over a burning candle to 1cm height what hapens?
Lifting the glass tumbler placed over a burning candle to a height of 1cm could disrupt the airflow around the candle, affecting its ability to receive oxygen. This may cause the candle flame to flicker, decrease in size, or even extinguish depending on how much air is allowed to reach the flame.
Is candle flame a source of light?
The flame of a candle is a source of light.
Why does a lit candle go out when a inverted beaker is on it?
When an inverted beaker is placed over a lit candle, the flame goes out due to lack of oxygen. As the candle burns, it consumes oxygen and generates carbon dioxide and water vapor. When the beaker is placed over the candle, it creates a closed system, limiting the supply of oxygen needed for combustion, causing the flame to extinguish.
Why a candle gets extinguish when a glass is put over it?
When a glass is placed over a candle, the candle flame burns up the available oxygen inside the glass. As the oxygen is used up, the flame is starved of oxygen and eventually goes out. This demonstrates the concept of oxygen depletion leading to extinguishing of the flame.
Why does a flame not get extinguished when a wire gauze was placed on top of it in a candle observation chemistry lab?
A flame is not extinguished when a wire gauze is placed on top of it because the flame is still exposed to oxygen. The gauze has holes, through which oxygen can flow. Additionally, oxygen can reach the flame from under the gauze. Consequently, the flame is not extinguished.
If a plant and a burning candle are placed under a bell jar will the candle burn?
No, the candle will not burn because the flame will consume the oxygen inside the bell jar, creating a vacuum and extinguishing the flame. Oxygen is necessary for combustion to occur, and without it, the candle cannot burn.
