1,Condensation is an endothermic process because the system is absorbing energy. 

2,The melting of ice is an exothermic process because the system absorbs energy. 
3,Heating water is an endothermic process which increases the internal energy of the system.

1.  False.  Condensation is exothermic, or losing energy.  This is because water vapor is turning into liquid water (a lower-energy state)

2.  False.  Melting of ice is endothermic because it is absorbing energy

3.  True.  Endothermic means energy is absorbed, and absorbing energy increases the internal energy of the system
