Visual Aid to Demonstrate Change of State and Gas Pressure with Temperature
Ghaffari, Shahrokh
Journal of College Science Teaching, v41 n1 p80-82 Sep 2011
Demonstrations are used in chemistry lectures to improve conceptual understanding by direct observation. The visual aid described here is designed to demonstrate the change in state of matter with the change of temperature and the change of pressure with temperature. Temperature is presented by the rate of airflow and pressure is presented by number of shots that collide with a sensor.(Contains 1 table and 3 figures.)
