Answer: The increase in temperature is 7.14°C
Step-by-step explanation:
To calculate the change in temperature, we use the equation:

where,
q = heat absorbed = 14.5 kJ = 14500 J (Conversion factor: 1 kJ = 1000 J)
m = mass of water = 485 g g
c = specific heat capacity of water = 4.184 J/g.°C
= change in temperature = ?
Putting values in above equation, we get:

Hence, the increase in temperature is 7.14°C
