Answer:

The proportion of light transmitted by glazing is specified by the Visible Light Transmittance, which is recorded as either TVw (visible transmittance of the window) or VLT (visible light transmittance). These terms are interchangeable, but in Australia, the Window Energy Rating Scheme uses Tvw in its ratings.

While the VLT/Tvw rating varies between 0 and 1, most double glazed windows rate between 0.3 and 0.7 , which means that between 30% and 70% of the available light passes through the window. The illustration above shows you how the view changes, as the amount of light getting through the window changes.

Table salt conducts electricity in water, but sugar does not. Explain why?

galben [10]

Answer:

Because sugar has no ions in the solution

Explanation:

Pure water contains very few ions, so it does not conduct electricity very well. When table salt is dissolved in water, the solution conducts very well, because the solution contains ions. When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution.

In basic words the more ions in the solution there is a better chance to conduct electricity.
