To calculate the amount of energy required to increase the temperature of a substance, we can use the formula:

q = m * C * ΔT

where:

q is the heat energy (in joules),

m is the mass of the substance (in grams),

C is the specific heat capacity of the substance (in J/g°C), and

ΔT is the change in temperature (in °C).

Given:

m = 245 g (mass of water)

C = 4.184 J/g°C (specific heat capacity of water)

ΔT = 81.6°C - 28.4°C = 53.2°C (change in temperature)

Plugging in the values into the formula:

q = 245 g * 4.184 J/g°C * 53.2°C

Calculating the value:

q ≈ 55480.392 J

Since the question asks for the energy in kilojoules (kJ), we can convert the result:

q ≈ 55.480392 kJ

Therefore, approximately 55.480392 kJ of energy is required to increase the temperature of 245 g of water from 28.4°C to 81.6°C.
