Mechanism and Application of the Induction Coil
The induction coil is a device for getting a high voltage from a low one. It was at one time used for X-ray tubes, and…
Classification and Production of Spectra through Excitation
1. Flame Spectra: The temperature of a Bunsen flame is high enough to vaporize certain solids. Thus if a piece of platinum wire is…
6 Fundamental Differences Between Light and Sound Wave
There are some basic and fundamental properties peculiar to a light and sound wave that differentiates one from the other. These differences account for the…
How Polarization in Water Voltameter Occurs
The water voltameter gives a very good credence to the idea of polarization. When the potential difference across the voltameter is less than 1.7volts, the…
Concise Description of Total Radiation Pyrometers
Total Radiation Pyrometers are less common compared to optical pyrometers and are available in different types such as the Fery Total Radiation Pyrometer and the…
Concise Description of Optical Pyrometers
Pyrometers are instruments used in measuring high temperatures. It has found use extensively in several industrial processes where they are used in temperature monitoring and…
Application of Joule-Kelvin Effect in Gas Liquefaction
Joule’s crude experiments on the expansion of a gas into a vacuum(free expansion) suggested that in such an expansion the gas lost no internal energy,…
Concise Description of How a Refrigerator Works
The action of a refrigerator depends on the absorption of its latent heat by a liquid, which can be referred to as the working substance….
How Regnault’s Dew-Point Hygrometer Works
Regnault’s dew point hygrometer is an instrument used in hygrometry to measure relative humidity. However many forms of dew point hygrometer have been devised, but…
