A balloon filled with 3.50 kg of water at a temperature of 22°C is dropped from rest from an airplane. The airplane is 8000 m above the ground. There is air resistance acting on the balloon, and just before hitting the ground, the balloon is traveling at a speed of 200 m/s. For this problem, you can ignore the balloon material (its mass, specific heat etc…) and just treat the balloon as 3.50 kg of pure water. Also, assume g is a constant 9.8 m/s^2 during the entire fall and that the system of the water + surrounding air is a closed system. Assume that all internal energy change occurs in the water. a) Find the temperature of the water in the balloon just before hitting the ground.  ( cm, water = 4186 J/kgK)

Ideal Gas Law

Ideal gas law states that the product of pressure and volume of a gas directly varies with the product of the number of moles, the universal gas constant, and the temperature of the gas.
