Question: A 434 g steel bucket contains 8.55 L of water at 13.3 °C. The bucket and water are in thermal equilibrium with each other. Part 1) How much energy needs to be added to the bucket to raise its (and its contents) temperature by 56.0 °C? Q= Part 2) A nugget of lead at 437 °C with a mass of 697 g is now added to the bucket (while it is at 13.3°C)....
