Question

1. during a power failure, blair lit four identical candles. he placed three candles very close together on a table, and one on a different table. when the power came back on an hour later, blair was surprised to see that the candles in the group were much shorter than the one by itself. there was also more melted wax around the base of each of the three candles. account for blair’s observation. what kind of candles should you keep on hand for emergencies?

Explanation:

When candles are grouped closely, the heat from each candle affects the others, increasing the local temperature around them. This higher - temperature environment causes the wax to melt faster, making the candles burn more quickly. For emergencies, slow - burning candles, such as those with a larger diameter or made of wax with a higher melting point, should be kept on hand as they will last longer.

Answer:

The grouped candles burned faster because the heat from each candle increased the melting rate of the others. For emergencies, slow - burning candles should be kept on hand.
