PRE-LAB QUESTIONS 1. When 3.0 kg of water is warmed from 10 °C to 80 °C, how much heat energy is needed?2.A calorimeter contains 100 g of water at 39.8 ºC. A 8.23 g object at 50 ºC is placed insidethe calorimeter. When equilibrium has been reached, the new temperature of the water and metal object is 40 ºC. What type of metal is the object made from?
