Applied science How do you determine how much gas remains in a cylinder? For cylinders containing compressed (non-liquefied) gas, gauge pressure falls as gas is used; Boyle’s law can be…

By altering the driving flow, the constriction size or the size of the opening, the Venturi effect can be used to mix gases or fluids to produce a fixed concentration….

The osmometer uses supercooling to measure the depression of the freezing point. Supercooling is the process of cooling a liquid without causing a change in state. It involves rapidly cooling…

As a liquid’s temperature rises, more molecules gain sufficient energy to leave the liquid and enter the vapour phase. This results in an increase in SVP. SVP continues to rise…

Applied science Describe the applications of non-electrical thermometers Liquid thermometers containing mercury are effective from −39°C to 250°C, while alcohol thermometers are effective from −117°C to 78°C. They are commonly…
