Air contains 78.08% nitrogen, 20.095% oxygen, and 0.93% argon. Calculate the partial pressure of oxygen if the total pressure of the air sample is 1.7 atm.

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.
