• The science behind a rice cooker is fascinatingly clever, yet painfully simple. In short, boiling water temperature plateaus due to the latent heat of vaporization. When the water is gone the temperature of the pot starts to rise. The rice cooker uses this principle to …

• I started using the old-fashioned analogue rice cooker after watching Technology Connection's video on how they work. The principle is clever: liquids at boiling point stay at boiling point, since any additional heat energy is used to change their state from liquid to gas. When …
