ENERGY OF MOLECULES
The enormous energy- and activity of molecules was explained by Professor F. P. Worley in his address on ultra-microscopic particles before the Auckland Institute and Museum in the University College Hall last evening. A number of highly interesting experiments was performed to illustrate Professor Worley’s remarks. To indicate the size of the minute particles of matter, the professor said that, were a sixpence divided into 1.000,000 layers, each layer would be much thicker than most molecules. Professor Worley also demonstrated how a little knowledge of science can be employed to puzzle those who knew even less. Taking two empty glass containers, he placed a drop of ammonia in one and a drop of hydrochloric acid in the other. When the containers were placed together, dense white fumes formed and filled the vessels. This was a trick once popular with conjurers. A man at the back of a hall would be told that the smoke would be caught on the stage, if he smoked a cigar.
