Mr. Wurtz performed a demonstration for his science students in a well-ventilated
room. He mixed together two samples of different white powdery substances in an
open beaker. The dry mixture soon became wet, and the students could smell
ammonia. The temperature of the beaker dropped dramatically, so much so that the
liquid that formed in the beaker began to freeze.
A liquid formed at the bottom of the beaker
The temperature of the mixture dropped dramatically
A gas with strong smell was released from the mixture
