Answer:
696.83 m/s
Explanation:
m = mass of water = 565 g = 0.565 kg
c = specific heat of water = 4186 J/(kg⁰C)
ΔT = Change in temperature = T₂ - T₁ = 80 - 22 = 58 ⁰C
v = speed gained by water
Using conservation of energy
Kinetic energy gained by water = heat required to warm water
(0.5) m v² = m c ΔT
(0.5) v² = c ΔT
(0.5) v² = (4186) (58)
v = 696.83 m/s
