2. Kara Less was applying her makeup when she drove into South's busy parking lot last Friday morning Unaware that Lisa Ford was stopped in her lane 30 feet ahead, Kara rear-ended Lisa's rented Taurus. Kara's 1300-kg car was moving at 11 m/s and stopped in 0.14 seconds. a. Determine the momentum change of Kara's car. b. Determine the impulse experienced by Kara's car. c. Determine the magnitude of the force experienced by Kara's car

H4. A zinc pot (coefficient of linear expansion : ) is filled with mercury at 100 °C, then having a 10.0 L capacity. Cools down to 0°C. Calculate the mass of mercury, measured at °C, that must be added so that the vessel is completely full (coefficient of volumetric expansion of mercury: ). Density of mercury at 0 °C; 13.6g/cm3.
** 16. If nitrogen gas and oxygen gas are combined in a tank, they will be at the same tem- perature and fill the same volume. a) Basing your explanation on the kinetic theory of gases, as derived in Section 15.1, explain why you would find the total pressure in the tank by adding together the indi- vidual pressures of the nitrogen and oxygen acting alone. This conclusion is known as Dalton's Law of Partial Pressures. b) A 1-m³ tank contains 0.8 moles of nitrogen and 0.2 moles of oxygen at 300 K. What is the total pressure in the tank?
None

A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a 1 atm pressure piston cylinder large insulated water bath. (See sketch at right.) water bath From previous experiments, this chemical reaction is known to absorb 222. kJ of energy. gases The position of the piston is monitored, and it is determined from this data that the piston does 291. kJ of work on the system during the reaction. exothermic Is the reaction exothermic or endothermic? x10 endothermic up Does the temperature of the water bath go up or down? down neither in Does the piston move in or out? out neither in Does heat flow into or out of the gas mixture? out neither How much heat flows? Be sure your answer has the correct number of significant digits.
