If you were burning candles in a science lab, what risks can happen?

You would have the risk of an explosion if the flame gets too near certain chemicals, because the fuel load and hazard levels in labs are very high. Labs, especially those using solvents in any quantity, have a very high potential for flash fires, explosion, rapid spread of fire, and high toxicity of products of combustion (heat, smoke, and flame).

An explotion could happen. Hope I helped.

Elias is almost correct. he just got it backwards.the correct answer is that it demonstrates elastic potential energy transforming into kinetic energy.

Where is the graph ?
