Angelo Battelli (28 March 1862 – 11 December 1916) was an Italian
scientist, notable for having measured
temperatures and
heats of
fusion of
non-metallic substances,
metallic
conductivities and
thermoelectric effects in
magnetic metals, and the
Thomson effect
The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when ...

Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to f ...
