(1) The mass of water when the water heater is full of water:
m=ρv=1×103kg/m3×100×10-3m3=100kg ,
(1) The mass of water when the water heater is full of water:
m=ρv=1×103kg/m3×100×10-3m3= 100kg,
Heat absorbed by water:
Absorption Q=cm△t=4.2×103J/(kg?℃)×100kg×(50℃-20℃ )=1.26×107J;
(2) If all electrical energy is converted into thermal energy, that is, Q absorbs = W electricity,

Answer: (1) When the solar water heater is full of water, it should absorb 1.26 × 107 J when the water temperature increases from 20°C to 50°C;
>(2) The water heater must operate normally for 140 minutes.
(3) The efficiency of this water heater is approximately 77.8%.
