The more air is in the jar, the longer the candle will be able to burn. So the candle in jar 3 probably burned for 4 minutes.
The candle in jar 4 would be able to burn much longer then the others, because it has no lid so air can come through and keep the candle burning.
While the sun does emit ultraviolet radiation, the majority of solar energy comes in the form of "light" and "heat," in the visible and infrared regions of the electromagnetic spectrum.
