What is the independent variable in the candle experiment?
1. For this experiment, the independent variable is the type of candle used – unscented, rose scented and apple scented. The dependent variable is the reduction in the candle’s length after 30 minutes. This is determined by measuring the height of the candle before and after allowing it to burn for 30 minutes.
Do white candles burn faster than colored candles experiment?
Most people seem to think that plain white candles will burn faster than those with added dyes. In reality, color makes little to no difference in how fast a candle burns. In fact, candle dyes can make a candle burn hotter in some cases, causing the colored candles to burn faster.
How fast does a candle burn independent variable?
| Question | Independent Variable (What I change) | Controlled Variables (What I keep the same) |
|---|---|---|
| How fast does a candle burn? | Time measured in minutes | Use same type of candle for every test Wind–make sure there is none |
What is the difference between colored candles and white candles?
Because paraffin wax is naturally white, a colored paraffin candle and a white paraffin candle are only different because a candle pigment has been added to the wax to create the color. Other wax types need white candle color added to create a white color.
Do white candles burn faster than colored candles bibliography?
Answer and Explanation: It turns out that white candles don’t burn faster than colored candles. In fact, the opposite is true. A larger wick will burn faster than a smaller wick. Certain types of wax, such as beeswax, are harder and will take longer to burn.
Which type of candle burns longest?
#10 – Double-wick candles and triple-wick candles are generally long lasting candles. As long as the wicks are evenly spaced and not too close to the edge of the container, then a double wick candle will burn more completely than a single wick candle — because all of the wax melts evenly.
What makes a candle burn faster?
Wax is the most important ingredient that makes a candle burn faster. Soft wax has a higher oil content and lower melt temperature; therefore, it burns faster. Typically, candles in jars have soft wax, and pillar candles have hard wax.
Which candle will burn the fastest science project?
Explanation. The colored candles are seen to burn less than the white ones as the colored ones have dyes that are nothing but chemicals which make the candles hotter and burn them quicker.
What makes a candle burn slower?
Adding salt serves the same purpose as putting the candle in the freezer—it slows down the rate at which the wax melts, giving you a longer, more economical burn. But it can also be helpful to keep the candle wick trimmed to about a quarter inch in length, because longer wicks tend to hasten burning.
Which candle wicks burn slower?
Wooden wick candles typically produce a lower, smoldering flame, which will consume your candle at a slower rate and thus burn longer!
What type of candle burns the longest?
Soy wax, which is made from hydrogenated soybean oil, and beeswax are the two longest lasting waxes, so they are considered the best wax for candles. While beeswax typically lasts longer, it is more difficult to work with because it has an extremely high melting point.
Which candle wax burns the fastest?
Soft wax has a higher oil content and lower melt temperature; therefore, it burns faster. Typically, candles in jars have soft wax, and pillar candles have hard wax.
