Based on the following passage, why might an architect choose to use a curtain wall? Office buildings and high-rises often include a curtain wall of glass, which requires advanced systems of fastening glass plates together. In a building with a curtain wall, the covering of the building does not serve a structural purpose; it is simply a façade that keeps out the elements. A curtain wall can be made of a number of different materials, such as aluminum, stone veneer, or glass.

It can be easily removed and frequently changed.

It is effective at resisting all types of weather including hurricanes and earthquakes.

It can reinforce the structural integrity of the building.

It can be made of lightweight, inexpensive materials.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
