Spirit designed to explore Planet Mars. It was for NASA's Mars Exploration Rover or MER mission which is an ongoing mission which includes two Mars rovers named Spirit and Opportunity. This is to discover the Martian surface and geology of the Planet Mars.
Answer is: 550,021 kWh of energy is needed to heat the water
V(water) = 51 gal = 51·3,78 = 189,3 L.
ΔT(water) = 25°C.
d(water) = 1000 g/L.
m(water) = V(water) · d(water)
m(water) = 189,3 L · 1000 g/L
m(water) = 189300 g.
Q = m(water) · ΔT(water) · C(water)
Q = 189300 g · 25°C · 4,184 J/°C·g
Q = 19800780 J = 19800,78 kJ ÷ 3600 = 550,021 kWh.
