Consider two cases:. Case 1: an ideal gas expands, reversibly adiabatically (under no change in entropy):
Case 2: the same ideal gas expands, but in this case the process occurs without change in Helmholtz Free Energy.
Case 3: the same ideal gas expands, but in this case the process occurs without change in Gibbs Free Energy.
Case 4: the same ideal gas expands, but in this case the process occurs without change in Gibbs Free Energy

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.

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
