The final temperature of water is 60°C

Explanation:

To calculate the final temperature of water, we use the equation:

$q=mc\Delta T$

where,

q = amount of heat absorbed = 8.4 kJ = 8400 J (Conversion factor: 1 kJ = 1000 J)

m = mass of water = 200 g

c = specific heat capacity of water = 4.2 J/g.°C

$\Delta T$ = change in temperature = T_2-T_1=T_2-50^oC

Putting values in above equation, we get:

$8400J=200g\times 4.2J/g.^oC\times (T_2-50^oC)\\\\T_2=60^oC$

Hence, the final temperature of water is 60°C
