1.) THe temperature of tap water is 20*C. During a bath, John fills a 320L bathtubwith water at 40*C. HOw much energy is used to raise the water temperature? (Specific heat capacity of water =4200 J Kg*-1*C*-1 and Density of water =1Kg L^-1)
最佳解答:
Mass of water = 320 L * 1kg L^-1 = 320kg Energy to raise 320 L from 20deg.C to 40deg.C = 4200 J kg^-1 C^-1 * 320kg * (40-20) = 26880 kJ
