Candles

You would typically need about 1 lb of wax to make a 1 lb candle. This allows for some extra wax to account for any loss during the melting and pouring process.

Candle color does not typically affect how fast a candle melts. The melting rate of a candle is more dependent on factors like the type of wax, wick size, and burning conditions. However, some fragrances or dyes in colored candles may affect burning time and intensity.

If you put your finger above a candle, you may feel the heat radiating from the flame and might sense some discomfort or pain if you hold your finger there for too long due to the heat. However, you won't typically get burned unless you touch the actual flame itself.

When a candle burns in a plentiful supply of air, the products of combustion are primarily carbon dioxide (CO2) and water (H2O). Additionally, small amounts of other byproducts such as carbon monoxide, soot, and trace amounts of other gases may also be produced.

The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.

The phrase "can't hold a candle to" originated in the 17th century, when it referred to an apprentice tasked with holding a candle to provide light for a more skilled worker. Over time, the expression evolved to mean that someone or something is not as good or skilled as another.

The main types of candle waxes are paraffin, soy, beeswax, and palm. Paraffin wax is derived from petroleum, soy wax from soybean oil, beeswax from honeybees, and palm wax from palm trees. Each type has its own characteristics and benefits for candle-making.

The fuel for a burning candle is wax, which is a hydrocarbon. When the candle burns, the wax is converted into carbon dioxide and water vapor through a combustion reaction. This process releases energy in the form of heat and light.

A candle jar in microbiology is a device used to create a microaerophilic environment for culturing bacteria that require low levels of oxygen to grow. The jar contains a lit candle, which consumes some of the oxygen and produces carbon dioxide, creating ideal conditions for these types of bacteria to thrive.

A wax candle can turn into a liquid when it is melted by heat. Once the melted wax cools down, it solidifies back into a solid state.

Candle wax whitener is a powder or liquid additive that can be mixed into melted wax to lighten its color. It helps to achieve a more opaque or vibrant hue for the candle when it solidifies.

Chemical energy in the match is converted to thermal energy, which produces heat to ignite the candle.

The melted wax from a lit candle is typically referred to as "candle drippings."

A burning candle goes off when covered by a glass cup because it uses up the available oxygen in the cup, creating a sealed environment with no oxygen for the flame to continue burning. This causes the flame to extinguish due to the lack of oxygen needed for combustion.

The melting point of candle wax varies depending on the type of wax used. Generally, paraffin wax (commonly used in candles) melts at around 120-150 degrees Fahrenheit (49-66 degrees Celsius). Soy wax, another common type, has a lower melting point of around 110-130 degrees Fahrenheit (43-54 degrees Celsius).

The energy in a candle comes from chemical potential energy stored in the wax. When the wax is burned, this energy is converted into light and heat energy through the process of combustion.

The burning temperature of a candle flame is typically between 1400-1600 degrees Fahrenheit (760-870 degrees Celsius). The temperature varies depending on the type of wax and additives in the candle.

As a candle burns, the total amount of chemical potential energy stored in the wax is converted into heat and light energy, so the total amount of energy remains the same.

The heat from the candle is transferred to your palm primarily through conduction. Conduction is the transfer of heat through direct contact between two objects at different temperatures. In this case, the heat is conducted from the candle's flame to your palm as they come into contact with each other.

A lit candle releases light energy in the form of visible light and thermal energy in the form of heat.

When a candle burns, chemical energy stored in the wax is converted into heat energy and light energy through a chemical reaction called combustion. The heat energy causes the wax to melt and then evaporate, while the light energy is emitted as a flame.

Yes, steel wool can burn under a candle flame because it is made of thin strands of steel that can catch fire when exposed to a heat source. The iron in the steel wool reacts with oxygen in the air when heated, causing it to ignite and burn.

chemical

Trace elements in candle wax can vary depending on the type of wax used. Common trace elements found in candle wax include hydrogen, carbon, oxygen, and impurities such as sulfur, nitrogen, and trace metals like iron, zinc, and copper. These elements can affect the burning characteristics and color of the candle.

The change of state is melting. When a candle wax is heated, it transitions from a solid state to a liquid state.
