  1. Question 1

    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?

    • A) 21000 J
    • B) 42000 J
    • C) 84000 J
    • D) 168000 J

    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.
