Do colored candles burn faster than white
arlik [135]
Maybe the other way around. But I am not sure. The only reason I would say white candles burn faster than colored is because they do not have as much chemicals in them (they don’t need to be dyed after all). However, if you want a long lasting candle, make sure the wick is good quality.

what can cause a decrease in soil quality of farm land that is left without crops during some months every year
mixer [17]

Answer:

Let the land lie fallow for a season

Explanation:

In Agriculture when a farmer has some problems with the quality of his soil due to continued planting all year round without allowing the soil rest, there seems to be loss of some of the nutrients that help crops grow and he is unable to grow crops on his field.

The best option is to allow the land low fallow with grasses and other plants growing and replenishing the soil.

In the proton-proton chain, four hydrogen nuclei are converted to a helium nucleus. This does not happen spontaneously on earth
SCORPION-xisa [38]

Four hydrogen nuclei are converted to helium nuclei in the proton-proton chain. This does not occur naturally on Earth because the process requires it. extremely high temperatures, pressures, and densities

The proton-proton chain is a series of reactions that fuses four hydrogen nuclei to form one helium nucleus. The energy is derived from the mass difference between the four hydrogen nuclei with higher masses and the single helium nucleus with lower masses. Energy is released when hydrogen is fused into helium: mass to energy conversion. Because mass is created during the proton-proton chain, energy is released. However, this is essentially the end of the story for the nuclear fusion reactions that occurred in the early Universe, known as Big Bang Nucleosynthesis.
