Oh, dude, a candle that's not lit is like a party pooper at a birthday bash. It's just a waxy cylinder chilling on a shelf, waiting for its moment to shine. Chemically speaking, it's made of stuff like paraffin wax and stearic acid, but for now, it's just hanging out, being all solid and unexciting.
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
SUGAR is a carbohydrate.If we talkk about its chemical properties,it is jst a simple molecule composed of glucose (or starch).
Yes, chemical properties can be determined only experimentally, as a consequence of chemical reactions. But, today chemists can made some predictions about chemical properties of a substance on the basis of existing data about chemical and physical properties.
What are the physical properties of unlit candle
the energy stored in an unlit candle is chemical potential energy, and it is stored in the bonds between the atoms in the hydrocarbons (wax) that make up the candle.
In an unlit candle, the qualitative observations would be its solid wax structure, the presence of a wick, and the lack of a flame or melted wax.
Potential energy is in an unlit candle, which is converted to heat energy, once the candle is lit.
an unlit candle frightens no monkey
The intrinsic properties of a candle include its chemical composition (such as paraffin wax or beeswax), its physical attributes like color and shape, and its ability to burn and produce light and heat. These properties are inherent to the candle itself and define its fundamental characteristics.
An unlit match contains chemical potential energy stored in the matchstick, specifically in the match head which contains chemicals that can undergo a chemical reaction (combustion) when ignited.
When a scented candle is lit, the heat from the flame causes the wax to melt and release the fragrance oils into the air, leading to a stronger smell. When the candle is unlit, the fragrance is contained within the wax and is not actively being dispersed into the air.
A stick of unlit dynamite contains chemical potential energy, which is released when the dynamite is ignited and undergoes a rapid chemical reaction.
I can tell you why. If you shine a torch on the top of the unlit candle it will begin to glow and change. I guess it may be to do with light sensitive elements in oils.
Candle wax is a physical property since it is a characteristic of the substance itself. Physical properties describe the appearance, composition, and behavior of a material without changing its chemical composition.
Candle wax is a mixture of different compounds, predominantly consisting of hydrocarbons like long-chain alkanes. It is not a pure substance because it contains various molecules with different chemical properties.
