Antibodies interact with only corresponding antigens by binding to them. When cells or molecules become coated with antibodies, the antibodies form cross-linkages and stick to each other causing clumping or agglutination of cells or molecules. Match the donor's RBC phenotype with the antibodies they induce in others.

#10. Consider the piston cylinder and tank shown. The piston cylinder contains 0.0102kg of air at 420K and 101kPa. The air is compressed to 390K and 158kPa. Heat is generated by the compression of the air and is transferred to a closed rigid tank. The tank initially contains 0.01m^(3) of water at 100deg C and a quality of 80%. The heat is transferred to the tank until the pressure is 400kPa. Determine (a) the total mass of the tank (b) the temperature at state 2 of the tank (c) define the tank as the system and find the heat transferred to the tank, in kJ (d) draw the process on P-v diagram (e)now define the system as the piston cylinder and determine the work input to compress the gas, in kJ #10.Consider the piston cylinder and tank shown.The piston cylinder contains 0.0102 kg of air at 420 K and 101 kPa The air is compressed to 390 K and 158 kPa.
