Why does it feel hot when you put your hand above a burnings candle?
The heat from the burning candle causes the air around it to warm up. When you place your hand above the flame, you are feeling the heat radiating from the flame onto your hand. This sensation is your skin detecting the higher temperature of the air near the flame.
Why if your hand is held high above a burning candle does it feel heat?
Even though heat rises due to convection, the energy from the flame travels in all directions and can reach your hand even when it is held above the candle. The heat radiates outward from the flame, which is why you can feel the warmth even if your hand is not directly above the flame.
Why the hot air above the burning candle rises and colder air flows to replace it?
The air is hotter above the flame because the carbon dioxide being generated by the flame is moving up due to convection, which states that hot air rises. An easier way to think of it is that smoke from a fire goes up, not sideways (unless the wind is blowing) so there is hot air above the flame, not beside it.
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.
What is the path of energy transformation when a burning candle turns a pinwheel?
The burning candle releases energy in the form of heat and light, which is then absorbed by the air molecules. These air molecules gain kinetic energy and start moving faster, causing them to push the pinwheel and make it rotate. So, the energy transformation path is: chemical energy (candle) → heat and light energy → kinetic energy (air molecules) → mechanical energy (pinwheel).
Why does it feel hot when you put your hand above a burnings candle?
The heat from the burning candle causes the air around it to warm up. When you place your hand above the flame, you are feeling the heat radiating from the flame onto your hand. This sensation is your skin detecting the higher temperature of the air near the flame.
Is a burning candle exothermic reaction?
Yes, a burning candle is an example of an exothermic reaction. When the candle wax reacts with the oxygen in the air, it produces heat and light energy as byproducts. This release of heat is what makes the candle flame feel warm to the touch.
Why does candle wax evaporate when the candle is burning?
Candle wax evaporates when the candle is burning because the heat from the flame causes the wax to melt and turn into a gas, which then evaporates into the air.
Why if your hand is held high above a burning candle does it feel heat?
Even though heat rises due to convection, the energy from the flame travels in all directions and can reach your hand even when it is held above the candle. The heat radiates outward from the flame, which is why you can feel the warmth even if your hand is not directly above the flame.
What is the word equation for a candle burning in the air?
The word equation for a candle burning in the air is: Wax + Oxygen → Carbon Dioxide + Water + Light + Heat.
What name is given to a process such as a burning candle?
The process of a burning candle is known as combustion. During combustion, the candle wax reacts with oxygen in the air to release energy in the form of heat and light.
When we blow any burning candle its puts out why?
because of the chemicals inthe air
What does candle wax react with?
Candle wax typically reacts with oxygen in the air when it is burning, producing heat, light, and carbon dioxide. The chemical reaction that occurs during the burning of candle wax is called combustion.
What is possible explanation as to why the candle went out?
The candle could go out if there is a strong draught of air, or if all the oxygen is used up by a candle burning in a sealed container.
What name is given to a process such as burning a candle?
The process of burning a candle is called combustion, which is a chemical reaction involving oxygen that produces heat and light. During combustion, the wax in the candle combines with oxygen in the air to release carbon dioxide and water vapor along with heat and light.
Is burning candle getting shorter physical or chemical change?
Burning a candle is a chemical change because the wax undergoes a chemical reaction with oxygen in the air to form new substances like carbon dioxide and water. This process results in the candle getting shorter as it burns.
What is burning candle it is physically Chang or chamically?
Burning a candle involves a chemical change, as the wax is being oxidized by the oxygen in the air to produce heat, light, carbon dioxide, and water vapor. This process is irreversible and results in the formation of new substances, which is characteristic of a chemical change.
