A155 g aluminum cylinder is removed from a liquid nitrogen bath, where it has been cooled to -196.0°c. the cylinder is immediately placed in an insulated cup containing 80.0 g of water at 15.0 °c. what is the equilibrium temperature of this system? if your answer is 0.0 °c, determine the amount of water that has frozen. (the average specific heat of aluminum over his temperature range is 653 j/(kg. k).

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is transformed ⇒ as it changes into other forms of energy.
