Heat energy released : 167.2 kJ
Further explanation
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
m = 2000 g
c = 4.18 J/ g ° C
∆t = 20 ° C
[tex]\tt Q=2000\times 4.18\times 20\\\\Q=167200~J=167.2~kJ[/tex]
