Air pressure decreases as elevation increases. Identify how the boiling point of water on top of a mountain would be different from its boiling point at sea level. Draw two models to show how the particle motion and the state of water on the mountain top and at sea level would change if you kept adding thermal energy to water that was already at 100°C. Label your models to show what happens to the temperature as the energy is added.

In which direction will the following reaction go if the standard reduction potentials are 0.80 v for ag/ag+ and –0.44 v for fe/fe2+? ag+ + fe → ag + fe2+ a.)forward b.)the reaction cannot occur. c.) not enough information is given. d.) reverse

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.

Write a paragraph that provides examples of each stage of volcanic activity, a description of the volcano, and facts about each stage.
