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.

Exactly 1.00 ml of an aqueous solution of hno3 is diluted to 100.0 ml. it takes 29.78 ml of 0.0142 m ca(oh)2 to convert all of the hno3 to ca(no3)2. the other product of the reaction is water. calculate the molarity of the undiluted hno3 solution. petrucci, ralph h.. general chemistry (p. 144). pearson education. kindle edition.
