... 19. The strip would bend, because the two metals will expand at different rates. 20. The glass is also expanding, which would cause it to look like the liquid is expanding less than it actually is. 21. Any time you force a gas to expand or be compressed, you’re likely to change the temperature of th ...

... Convection: Convection happens when a fluid comes in contact with an object whose temperature is higher than that of the fluid. Heat is transferred through the flow of the fluid. Radiation: Heat can be exchanged via electromagnetic waves, called thermal radiation. It does not need a medium. ...

... The sun’s light falls upon the earth at varying angles depending upon the time of year. As illustrated below, summer sun is ’high’, winter sun is ‘low’. This offers opportunities to control the amount of solar gain, e.g moderate summer heat/gain and maximise winter heat/gain. ...

Insulated glazing
Insulated glazing (IG), more commonly known as double glazing (or double-pane, and increasingly triple glazing/pane) is double or triple glass window panes separated by a vacuum or other gas filled space to reduce heat transfer across a part of the building envelope.Insulated glass units are manufactured with glass in range of thickness from 3 mm to 10 mm (1/8"" to 3/8"") or more in special applications. Laminated or tempered glass may also be used as part of the construction. Most units are manufactured with the same thickness of glass used on both panes but special applications such as acoustic attenuation or security may require wide ranges of thicknesses to be incorporated in the same unit.
