题将-10℃、4kg的冰和20℃、5kg的水混合,求热平衡后的温度及冰和水的质量各是多少?(不计热量损失,水的比热c水=4.2×103J/(kg·℃),冰的比热c冰=2.1×103J/(kg·℃),冰的熔化热K=3.34×105J/kg)
Mix the water at -10°C and 4kg with water at 20°C and 5kg. What is the temperature and the quality of the ice and water after the heat balance? (Excluding the heat loss, the specific heat of the water c = 4.2 × 103J/( Kg · °C), specific heat of ice c ice = 2.1 × 103J/ (kg · °C), the heat of fusion of ice K = 3.34 × 105J/kg)
