Answer:
kJ = 1000J
Step-by-step explanation:
The formula q = 375 g × 25 C × 4.186 J / (g×C) = 39,243.75 J represents the heat in Joules, m the mass in grams, difference of temperature in Celsius degree, and 4.186 J/(g×C) is the specific heat of water. I assumed the water is liquid from and will remain liquid). Approximately 39.24 kJ once you round and transform to kJ = 1000J.
