Explanation:
Detailed explanation-1: -Q = U – W Therefore, the increases in internal energy U = 120 KJ/kg.
Detailed explanation-2: -Answer: 10450 J or 2500 calories of heat energy are required to raise the temperature of 25 grams of water from 0 degrees C to 100 degrees C.
Detailed explanation-3: -The specific heat capacity of water is 4, 200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4, 200 J to raise the temperature of 1 kg of water by 1°C.
