1. Calculate q when 29.6 g of ice is cooled from −26.2°C to −78.3°C (cice = 2.087 J/g·K)? 2. A 233−g aluminum engine part at an initial temperature of 11.77°C absorbs 80.4 kJ of heat. What is the final temperature of the part (c of Al = 0.900 J/g·K)? 3. A 24.0−g sample of ethylene glycol, a car radiator coolant, loses 510. J of heat. What was the initial temperature of the ethylene glycol if the final temperature is 32.5°C?...
A calorimeter is filled with 28.3g of radiator coolant, ethlylene glycol at 20.1 degrees Celsius. A 15.2 g block of Al at 86.2 degrees celsius is placed into the calorimeter. Assuming the heat capacity of the calorimeter is neglible what will be the final temperature for the coolant and the aluminum block. (c of ethylene glycol -2.42 J/mol g*k, c of aluminum = .900J/g*K)
