The specific heat capacity of water is 4200 J/kg°C. How much heat is required to raise the temperature of 2 kg of water by 5°C?
Q1. The specific heat capacity of water is 4200 J/kg°C. How much heat is required to raise the temperature of 2 kg of water by 5°C?
Answer: 42000 J
Explanation: Q = mcΔT = 2 kg * 4200 J/kg°C * 5°C = 42000 J. Other options miscalculate or use wrong specific heat capacity.
