A burning candle is covered by a jar as shown in the picture. The whole arrangement has a mass of 500 g. What will be the approximate mass of the arrangement when the candle is completely burnt, after four minutes?
But everything that was inside the jar at the beginning is STILL inside the jar when the candle stops burning. Nothing new came into the jar, and nothing went out of it. So the mass is STILL the same 500 grams.
