The Standard enthalpy of vaporization of water at 100.0
oC is 40.66 KJ*mol-1. The Cp,m
values for the liquid and the vapor water are, respectively, 75.3
and 33.58 J*K-1*mol-1. Assume that the heat
capacities are independent of temperature, and that the vapor
behaves as an ideal gas.
a) Calculate
sys in taking one mole of liquid water at 25.0
oC and 1.00 atm to gaseous water at 95.0 oC
and 0.500 atm.
b) Assume that the temperature and pressure of...

A ball is thrown straight up at speed in the presence of gravity. (a) Ignoring air resistance at first, what is the maximum height the ball reaches? (b) Now include Newtonian (quadratic) air resistance, with drag coefficient c. Letting the direction point upwards, write down the equation of motion (be careful with the signs). (c) Solve the equation of motion to find v(t)(= (t)). Remember to check that v(0) = . (d) Without integrating anything yet, calculate the time at...

4. A spring is hanging vertically with its bottom at a height of 1 m. We attach a 1 kg mass to the spring, and see that, after we gently lower it and let go, the bottom of the spring is at height of 0.95 m. Draw an energy interaction diagram starting at the moment the mass is attached and ending when the mass comes to rest. What is the value of the spring constant for this spring? Part 1:...
