Imagine that you are climbing a mountain.
(a) Is the distance you travel to the top a state function? Why or why not?
(b) Is the change in elevation between your base camp and the peak a state function? Why or why not?
What is the gas pressure (in atm) inside a 2.43-L bulb that contains 2.88-g of Ne at a temperature of 32.9 C?
Two evacuated bulbs of equal volume are connected by a tube of negligible volume. One bulb is placed in a 200K isothermal bath and the other in a 300K bath, and then 1.00 mole of an ideal gas is injected into the system. Find the final number of m..
