  2. Voltage reduction - Wikipedia

    en.wikipedia.org/wiki/Voltage_reduction

    Even some resistive loads provide only short-term benefits. A phenomenon known as load diversity plays a role in voltage reduction and can counteract its effects on occasion. The concept of load diversity can most easily be explained with an example. In your neighborhood, it is unlikely that all of the homes' water heaters are on at the same time.

  3. Optical properties of water and ice - Wikipedia

    en.wikipedia.org/wiki/Optical_properties_of...

    The refractive index of water at 20 °C for visible light is 1.33. [1] The refractive index of normal ice is 1.31 (from List of refractive indices).In general, an index of refraction is a complex number with real and imaginary parts, where the latter indicates the strength of absorption loss at a particular wavelength.

  4. Electromagnetic absorption by water - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_absorption...

    Water vapor concentration for this gas mixture is 0.4%. Water vapor is a greenhouse gas in the Earth's atmosphere, responsible for 70% of the known absorption of incoming sunlight, particularly in the infrared region, and about 60% of the atmospheric absorption of thermal radiation by the Earth known as the greenhouse effect. [25]

  5. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes

  6. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    The gaseous phase of water is known as water vapor (or steam). Visible steam and clouds are formed from minute droplets of water suspended in the air. Water also forms a supercritical fluid. The critical temperature is 647 K and the critical pressure is 22.064 MPa. In nature, this only rarely occurs in extremely hostile conditions.

  7. Radiation pressure - Wikipedia

    en.wikipedia.org/wiki/Radiation_pressure

    Due to the law of conservation of momentum, any change in the total momentum of the waves or photons must involve an equal and opposite change in the momentum of the matter it interacted with (Newton's third law of motion), as is illustrated in the accompanying figure for the case of light being perfectly reflected by a surface. This transfer ...

  8. Does Gatorade Hydrate You? - AOL

    The verdict when it comes to if Gatorade is hydrating is this: It absolutely does hydrate the body and can even do so more effectively than water. But that doesn’t mean you should drink it ...

  9. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    The change in pressure over distance dx is dp and flow velocity v = ⁠ dx / dt ⁠. Apply Newton's second law of motion (force = mass × acceleration) and recognizing that the effective force on the parcel of fluid is −A dp. If the pressure decreases along the length of the pipe, dp is negative but the force resulting in flow is positive ...
