If thermal expansion occurs on a hot day the tracks will expand. Leaving a small space for the tracks to expand into means they will not buckle. The water level in the capillary tube is initially ...

The laser beam locally heats the water reducing its viscosity. When combined, the effects of thermal expansion and a viscosity gradient cause the water to flow along the light path in the opposing ...

Scientists have developed a groundbreaking material that barely changes size with temperature, defying the usual expansion of ...

If you love a good, hot soak in the bath or a steamy shower, you probably have your water heater to thank. Water heaters are often essential for keeping hot water steadily flowing in your home ...

(Courtesy: M Dove and L Li/Matter) The anomalous and ultra-low thermal expansion of cordierite results from the interplay between lattice vibrations and the elastic properties of the material. That is ...
