Coach Fontana has ordered a special game ball that has been specially advertised to have a permeable needle hole which allows air to automatically inflate the ball. Using your
knowledge of partial pressure systems and gas diffusion, explain how this game ball
defies the laws of partial pressure systems, assuming the ball meets the mmHG pressure
standard of 776 mmHg and the atmospheric pressure is 760 mmHg. (6pts)

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
