Fill in the (blanks)
Most elements are (blank). The (Blank) elements on the left side of the stairsteps line on the (blank) of elements are metals. Some physical properties of metals are (blank) "shininess", good conductors of (blank) and (blank), and can be hammered into (blank) sheets. Non-metals are found to the (blank) of the stair-step line on the Periodic table of elements. The characters of nonmetal are (blank) to those of metals. Nonmetal have a dull (blank) or (blank). Nonmetals also break easily and are not (blank) or (blank).Metalloids that are on (blank) sides of zig-zag line have both properties of metals and nonmetals. Metalloids can be or dull and can conduct heat and electricity (blank) well.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
