07 – Two candles for the perfect cup of punch?

Elf Elfis is in charge of keeping a pot of warm punch cozy for the elves’ winter party. The punch is heated by placing candles under the pot.

He knows that when the room temperature is 22 °C and he places one candle under the pot, the punch reaches 32 °C. Elf Merry-Linn explained that the punch loses heat to the room at a rate proportional to the square of the difference between the punch temperature and the room temperature.

Curious to see the effect of more heat, Elfis decides to place two candles under the pot.

What will the temperature of the punch then approximately be with two candles under it?
