The specific heat capacity of water is 4200 J / kg * C. This means that to heat 2 kg water by 1 degree Celsius, an amount of heat is required in ..
Q-?
c = 4200 J / (kg * ° С)
m = 2 kg
∆t = 1 ° C
Decision
Q = c * m * ∆t
Q = 4200J / (kg * ° С) * 2kg * 1 ° С = 8400J
8400J is 8,4kJ (8400/1000)
Answer: 8.4kJ
