Question
Energy in Thermal Processes Pls answer no.1, round the final answer to four decimal places
1. Show that the temperature -40°C is unique in that it has the same numerical value on the Celsius and Fahrenheit scales. 2. A newly constructed steel bridge has a length of 518 m. How much will its length change between temperature extremes of -20°C and 35°C? 3. Equal 0.750 kg masses of lead and tin at 65.0°C are placed in 1.00 kg of water at 18.0°C. What is the equilibrium temperature of the system? 4. A 130.0-g cube of ice at 0°C is dropped into 1.0 kg of water that was originally at 85°C. What is the final temperature of the water after the ice has melted? 5. What mass of water at 25.0°C must be allowed to come to thermal equilibrium with a 1.85-kg cube of aluminum initially at 1.50 x 102°C to lower the temperature of the aluminum to 65.0°C? Assume any water turned to steam subsequently recondenses.
