Steam enters the turbine at 3 mpa and 350c and is condensed in the condenser ar a pressure of 75kpa heat is supplied to the steam in a furnace maintained at 1000 k and waste heat is rejected to the surroundings at 300k determine (a) the exergy destruction associated with each of the 4 processes and the whole cycle and (b) the second law efficiency of this cycle

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

hurricanes form in warm water
