Calculate the heat transfer, in kJ, when 1.287 kg of chicken breast (specific heat capacity = 1.82 J g^-1 °C^-1) is removed from a freezer at -17.3 °C and allowed to warm up to 0.00 °C. You need not be concerned about melting of ice or any other phase changes.

Step 1: Calculate the change in temperature

ΔT = (0.00°C - (-17.3°C)) = 17.3°C

Step 2: Calculate the heat transfer using the formula:

q = m × c × ΔT

where q is the heat transfer, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

Substituting the given values:

q = (1.287 kg) × (1.82 J g-1 °C-1) × (17.3°C) = 40.5 kJ

Therefore, the heat transfer is 40.5 kJ (Option D).
