Answer:
670400 J
Explanation:
m = mass of water = 2 kg
T₀ = initial temperature of water = 20 ºC
T = initial temperature of water = 100 ºC
c = heat capacity of water = 4190 J /kg ºC
Q = energy needed to raise the temperature of water
Energy needed to raise the temperature of water is given as
Q = m c (T - T₀)
Inserting the values
Q = (2) (4190) (100 - 20)
Q = 670400 J
