Answer #1

A cologne is mainly compose of volatile compounds, when you store it in the refrigerator you are lowering the vapor pressure of those compounds, thus you are assuring the components of the fragance to remain as liquid for a long period. In the other hand at low temperatures some compound (like the ones used to fix the fragance) can cristalize and you will ruin the cologne. Also the sudden change of temperature by the time you take it out from the fridge can cause a several lost of the volatile compounds, and a common refrigarator usually has high humidity which can affect the cologne.

The smell will persist, but the cologne is very probable to become useless.

A rigid, insulated vessel is divided into two compartments connected by a valve. Initially, one compartment, occupying 1.0 ft3, contains air at 50 lbf/in2, 500oR, and the other, occupying 2.0 ft3, is evacuated. The valve is opened and the air is allowed to fill both volumes. Assume the air behaves as an ideal gas and that the final state is in equilibrium.   Determine the final temperature of the air, in oR, and the amount of entropy produced, in Btu/oR.

A sample obese adult males were randomly divided into two groups in a lifestyle change program. In the experimental group, participants were involved in a vigorous 20-minute-per-day exercise program and also given instructions on the importance of diet. The control group only received the diet instructions. The hospital administrators predict that exercise plus diet instruction will reduce LDL cholesterol levels. Below are the LDL cholesterol data after two months in the program. What can be concluded with α = 0.10?...

Consider two stores operating along a one (1) mile street, one at the left end and the other at the right end. Both stores sell a single product, which costs $10 to produce (c = $10). Transport costs for each consumer = $5 per mile (t = $5). There are N = 100 consumers spread out equally along the street. Prices are set at a point that ensures all consumers are serviced. Assume prices are set simultaneously. The profit-maximizing price...
