Hello, I would need urgent advice with one task that I can't calculate. Please explain: When hardening steel, a hot object is immersed in a container of cold water. What will be the resulting water temperature if we immerse a steel object weighing 1.6 Kg and a temperature of 900 ° C in 15 liters of water at a temperature of 20 ° C? Thank you in advance for the answers :)
