1. If an iron rod initially at 27.6°C comes into thermal contact with an identical rod at 54.2°C, what will be the final temperature of both rods at equilibrium? Enter the correct numeric value with the appropriate number of significant figures. Express scientific notation like 4.29E-15 °C Grade This Exercise 2. To measure the caloric content of a new breakfast bar, you burn a 1.40 g sample in a calibrated bomb calorimeter (9.00 kJ/°C). During the burn, the temperature of the calorimeter rises from 25.4 °C to 27.7°C. If the serving size is 59.0 g, many Calories (kcal) are contained in each serving? how Enter the correct numeric value with the appropriate number of significant figures. Express scientific notation like 4.29E-15 Calories Grade This Exercise 3. When 15.0 mL of water at 11.0 C is combined with 10.0 mL of water at 82.0 C, what is the final temperature of the water?. The specific heat of water is 4.184 J/g/K and its density is 1.0 g/mL. Enter the correct numeric value with the appropriate number of significant figures. Express scientific notation like 4.29E-15 c.
