Which are properties of both a gas and a plasma? check all that apply. (1)can change shape to conform to a container (2)has a rigid shape that does not change easily (3)is made up of free-moving ions and electrons (4)is compressed more easily than other states (5)has particles that can wiggle but cannot move (6)has particles that move freely from place to place (7)will expand to completely fill a closed container

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.

Which of the following is the best name for mgcl2

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.
