Use the Clausius-Clapeyron relation to find the slope of the liquid-gas phase transition line at the natural boiling point of water (i. e. P = 105 Pa, T = 373 K). Assume that the water vapor is an ideal gas, and that the water has mass density rho = 958 kg/m3 . (You’ll also need that each molecule of water has mass m = 3 × 10−26 kg.)

Aperson touches a large chunk of ice with their hand and remarks, “this is making me cold.” explain what this person is feeling. is the ice transferring “cold” to the person? is there a heat transfer occurring? explain.

An electron and a proton are held on an x axis, with the electron at x = + 1.000 m and the proton at x = - 1.000 m. part a how much work is required to bring an additional electron from infinity to the origin? express your answer with the appropriate units. part b if, instead of the second electron coming in from infinity, it is initially at x = + 20.00 m on the axis and is given an initial velocity of 100.0 m/s toward the origin, does it reach the origin? part c how close to the origin does it come?
