Part 1. A glass bottle, which is hal-tilled with water, has a balloon attached to its opening. The bottle is placed in a hot water bath for some time. Explain the change to the sere or the balloon
based on the kinetic molecular theory.
Part 2. What would most likely happen to the balloon if the bottle was then placed into a jar of cold water with ice cubes? Explain your answer based on the kinetic molecular theory
In both cases, assume the balloon is attached tightly enough so that air does not escape the system. (8 points)

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.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
