In order for someone to shape steel into a sword’s blade, it is necessary to heat and cool the steel. This is often done using a large container of water. Assume a container of water is initially at room temperature (23°C) and the 7500 g steel blade of the sword is at 210°C. After the blade is placed into the water it comes to a final temperature of 25 °C. What is the approximate mass of the water?
