A person wants to cool down her bath water so she does so by adding 5.0 Kg of ice at 0°C to 75.0 Kg of water at 70°C. What would the final temperature of the water be ? Lf = 333 KJ/Kg & cH2O =4186 J/Kg°C

An aluminum cup of 93 cm³ capacity is completely filled with glycerin at 19°C. How much glycerin will spill out of the cup if the temperature of both the cup and glycerin is increased to 39°C? (The linear expansion coefficient of aluminum is 23 × 10-6 1/C°. The coefficient of volume expansion of glycerin is 5.1 × 10-41/Cº.) Number Mi Units

In an insulated container, you combine hot metal with ice. The ice starts at -20 degree C. The copper starts at 900 degree C. When 15 kg of the copper is combined with an unknown amount of ice, the system reaches equilibrium as soon as all of the ice has boiled to become steam. What is the final temperature of the copper?

An aluminum cup of 120 cm³ capacity is completely filled with glycerin at 16°C. How much glycerin will spill out of the cup if the temperature of both the cup and glycerin is increased to 37°C? (The linear expansion coefficient of aluminum is 23 x 10-6 1/C°. The coefficient of volume expansion of glycerin is 5.1 x 10-4 1/C°.) Number i 2.1 Units cm^3

Question 11 After some time, you pour 0.5 kg of milk, whose initial temperature was 5°C. What will be the final equilibrium temperature of this system? Let: 1.5 kg of coffee, originally at 90°C, is placed into a .3 kg aluminum cup. J Ccoffee = 4186 kg K J CAI = 500 kg K J CMilk = 3000 kg K Question 12 A solid steel sphere of radius 50 acts as a perfect radiator, calculate the amount of heat it will radiate after 1 min. cm is heated to 3000 K. If the sphere
