375 g of water at 90°C &199 g of glycerin at 47°C are pouredinto a 253 g copper cup at 68°C.Assuming these three make up a closed (or isolated) system,determine the final temperature of the system. The specific heat ofwater is 4186 J/kg·°C. The specific heat of glycerin is2410 J/kg·°C. The specific heat of copper is 387J/kg·°C.
