Click to add title How much heat is required to change a 400.0 g ice cube from ice at 20°C to steam at 120°C? (Water: C-1 cal/g °C; 4 = 79.7 cal/g: -539 cal/g: ice: G-0.50 cal/g °C, steam: -0.480 cal/g °C). II.1. 100 C 11.2. If you remove 1000 cal from 1.5 g of steam at 100°C held in a calorimeter, what will you have left in it? Cw = 1 cal/g °C; 4 = 79.7 cal/g; L = 539 cal/g; ice = 0.50 cal/g °C). 0C 11.3. You placed 350.0 g of ice at -25.0 "Cinto a Styrofoam calorimeter (no metal can is there]. Then supplied 150.0 kcal of heat. What will you find there in the calorimeter when the thermal equilibrium will be reinstated? (Water: Cw = 1.00 cal/g °C; Lf = 79.7 cal/g: Lv = 539 cal/s; ice: C = 0.500 cal/g °C, steam: Cs = 0.480 cal/g °C). 1.4. Your lab partner supplied 950.0 calories of heat to the system before you arrived. You notice that 130.0 g of water in the 45.0g aluminum calorimeter has temperature 35.0°C. a. what did he have in the calorimeter at the beginning of the experiment? b. How much heat you need to supply to the system to evaporate all the water? 11.5. Your lab partner supplied 950.0 calories of heat to the system before you arrived. You notice that 130.0 g of water in the 45.Og aluminum calorimeter has temperature 35.0'C. a. what did he have in the calorimeter at the beginning of the experiment? b. How much heat you need to supply to the system to evaporate all the water? 11.6. An Aluminum rod is 20 cm long at 22°C and has a mass of 350 g. If 10.0 kl of heat energy are added to the rod, what is its new temperature and what is the final length of the rod ? Specific Heat: CAL = 900 J/kg. C. Coefficient of thermal expansion: all = 24 x 10-6"C-1)
