What are house spirits? any good cocktails to reccomend?
House Spirits are the main basic spirits used at the bar for basic mixed drinks. They usually include Vodka, White Rum, Gin, Bourbon, Tequila and often a Scotch. Basic mixed drinks usually include a spirit and a mixer (EG Gin & Tonic, Bourbon & Coke, Rum & Pineapple, Vodka & Lemonade) Depending on where you are going, they can be either cheap unheard-of brands, good household names (EG Smirnoff Red, Bacardi, Gordon's, Jim Beam, any decent Tequila, Johnnie Walker Red), or at some bars even premium spirits. For instance at my bar we have Smirnoff Black Label, Bacardi, Tanqueray Gin, Maker's Mark, José Especial & Johnnie Walker Black Label as house spirits. There are plenty of great cocktails out there. Note that there is NOTHING wrong with asking the bartender for a recconmendation - it is entirely unnecessary to point out your naivity. The bar will probably have a cocktail menu with a few populars & classics, and maybe some signatures (always worth a try). If it's a good, well-stocked cocktail bar order my favourite - a Caipirinha, though they may not have Cachaca, in which case try a Caprioska. Have fun! (Thursdays, $5 before 11... you in Sydney?)
Why does black colour absorb light while white colour reflects light?
White reflects all wavelengths diffusely (the reflected rays go every which way). Silver (e.g., a mirror) reflects all wavelengths specularly (the reflected rays bounce off nicely).Now, metals do not necessarily always look like mirrors - they are often bumpier than that, so their reflection is a little bit diffuse as opposed to totally specular.Reflection of all wavelengths can be explained by band theory, which assumes that overlapping energy levels form bands. In metallic substances(Silver,white color) empty conduction bands can overlap with valence bands containing electrons. The electrons of a particular atoms are able to move to a higher-level state, with little or no additional energy. The outer electrons are said to be "free," and ready to move in the presence of an electric field. The highest energy level occupied by electrons is called the Fermi energy, Fermi level, or Fermi surface.Above the Fermi level, energy levels ar empty (empty at absolute zero), and can accept excited electrons. The surface of a metal can absorb all wavelengths of incident light, and excited electrons jump to a higher unoccupied energy level. These electrons can just as easily fall to the original energy level (after a short time) and emit a photon of light of the same( considered) wavelength.Black thing that absorbs incident electromagnetic radiation. Sometimes it's about chemical, via a variety of processes such that the electrons are excited by the light and eventually re-emit it in a non-visible wavelength.Black body is white body !!!sometimes white body appears as black body and black body appears as white body. A black-body can absorb all the radiation falling on it(light at all wavelengths) and appears black when cold. When it gets heated it can emit radiation at all wavelengths like a heated piece of metal. The hotter it gets the higher the photon frequency (energy) and so a shorter wavelength. Hotter objects emit more total radiation per unit surface area. This is not the same as photon absorption and emission of normal electron arrangements that fall within certain energy levels. As a black body heats up the electrons get more and more excited like a light bulb. At first red light and then the full spectrum. As all the colors mix it goes from red to orange to white. You don't see the greens and blues because they mix.
Metal roof is full of condensation how do i stop it from stop sweating?
You could put 27 "super absorbent" car tires on your roof, lol, but that wont do a lick of good. Get a cross breeze going with a fan or insulate the underside of the roof with ridgid foam leaving a airgap between the metal and the foam board sheets, that should do the trick. they sell a roll of what looks like silver bubble wrap at hardware and home stores, this wrap is made to insulate metal builings but it is a bit pricey compared to the foam board sheets. A fresh coat of roof coating (if it needs it) will help also, I use the white coating it reflects more of the suns rays then the aluminum coating. Good luck
What are the different types of sun rays?
The Sun emits light over a broad range of the electromagnetic spectrum, but it is strongest (from its outer regions that we can see, anyway) in the middle of the “visible light” portion. The Sun’s rays also contain strong ultraviolet and infrared components, with some x-rays, microwaves, radio waves, etc.Of course deep inside the Sun (the core) are vastly higher-energy environments more dominated by gamma rays, too; those rays — parcels of energy — tend to be re-absorbed and re-emitted over and over on their way from the core to the surface, frequently stepping down in re-emitted energies, until the “surface” is dominated by visible light emission.If you split up just the visible-light portion of the Sun’s rays into its component colors, you can get a nifty image like the following:APOD: 2000 August 15The narrow dark bands in that rainbow that seem at first to be “missing” are not, really, but instead demonstrate that the “surface” (photosphere) of the Sun that we see most readily from the outside is not actually its outermost layer. Between the photosphere and Earth (and our eyes) is a cooler layer of gaseous material that re-absorbes specific components of the light being emitted from underneath. The placement (color) and strength of these “dark” absorption features is actually a kind of unique “fingerprint” for the Sun’s chemical composition.In other words, while a lot of stars out there may have very similar overall colors to our Sun, if you were ever lost in deep space, you might still be able to find your way home by scanning around for that one little yellow-white star with exactly that elemental make-up — with a visual-spectrum fingerprint image that matches (the APoD link, above).
Heating of steel roof by sun is convection or radiation?
Whereas radiant barriers reflect radiated heat back to the roof deck raising the temp of the roof deck & shingles to radiate more heat back to the sky, the convection & conduction around the attic back into the attic still raises attic temps. Cool roofs radiate the heat back to the sky without the intervening complexity of roof deck- the surface of the roofing stays cooler, the roof deck stays cooler, and attic stays cooler, since the roof deck isn't running as hot. Cool roof materials do work measurably BETTER than radiant barriers, and are a sufficiently cheap improvement that independent of insulation levels or where the ducts are located, they're cost effective at almost any R-value.steel purlins
Corel Paint Shop Pro (tutorials)?
Does anyone know how to make an object (in a image) 3d like its coming out of the photo!? I remember seeing examples from another program off the internet...but I can't remember the website!?!
