2. A construction worker drops a hot 100-g iron rivet at 500 °C into a bucket containing 500 g of mercury at 20°C. Assuming that no heat is lost to the surroundings or the bucket, what is the final temperature of the rivet and mercury? 3. An unknown liquid of mass 400 g at a temperature of 80°C is poured into 400 g of water at 40°C. The final equilibrium temperature of the mixture is 49°C. What is the specific...
1 kg of water at 70 oC is poured into a 1 kg copper cup initially at 20 oC. The specific heat of copper is ccopper= 390 J/kgoC⋅ and that of water cwater= 4,186 J/kgoC. What will be the equilibrium temperature of the system? In the previous problem, how much heat will the cup receive during this process
1 kg of lead shot at 98.1o C are poured into 1 kg of water at 25.0o C. Find the final temperature (in oC) of the mixture. Use cwater = 4187 J/kg oC and clead = 128 J/kg oC.
1. A 325 g iron bucket contains 527 g of water, both at 21.6 oC. A 855 g piece of hot steel (T = 352 degrees Celsius) is added to bucket at the same time 295 g of ice at -22.2o C is added. Determine if all the ice melts. If so, what is the final temperature of the mixture? If not, how much of the ice melted? 2.Two wind instruments, one open and one “closed,” are played on day...
