Question

Explain why a hurricane thrives over warm water but dissipates over cold water. A hypothetical substance exhibits a vapor pressure of 200 torr at 40 degree C, and boils at 80 degree C at 1 atm. The triangle point is at torr at 20 degree C. The substance melts at 30 degree C at 1 atm and the solid state exhibits a vapor pressure of 50 torr at 10 degree C. Draw a phase diagram of the substance. Devise your own scale Label the regions where (s), (g), (l) states exist. Which is denser the liquid or the solid state, and why? Is the liquid state stable at STP? KF has the same type of crystal structure as Nacl. The unit cell length in KF is 5.39 A. The sketch on the right depicts more than one unit cell. Draw lines connecting the centers of some anions, in a cubic pattern defining one unit cell How many K, and how many F atoms are present in one unit cell? Calculate the mass of the atoms in one unit cell Calculate the density of the KF based on the unit cell in g/cm3
