Q. A 4.00 kg model rocket is launched, expelling 46 g of burned fuel from its exhaust at a speed of 590m/s. What is the velocity of rocket after the fuel has burned? Hint: overlook the external forces of gravity and air resistance.

Q. Water evaporates from salt solution and leaves behind salt crystals that have the higher degree of molecular order than the more at random moving molecules in the salt water. Has the entropy principle been violated? Why or why not?
