Does domestic/household used kerosene oil which is available in blue color (In India) can change its color over the due course of time say 8-10 years if keeping in plastic bottle? If so, in which color it will be turned to change, yellow or transparent or any other color. Please provide me the reply with strong technical approach. Since it has been asked during an interview. Please reply fast. I will be thankful to you if anyone can provide the supporting journals/write-ups/reference to favour of response.
