In the gas phase, the proton affinitiesof phosphinesdecrease in the following order (CH3)3P>(CH3)2PH>CH3PH2>PH 3. Discuss the basicity in terms of steric/electronic effects. In aqueous solution, the order is reversed. Discuss what is likely responsible for the reversal in the trend.

Freezing 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.
