9) balloon is alled with helum gas which is lighter than air Which of the (A·B, or C) shows the new volume of the balloon when the following changes are made? voleme a. The balloon floats to a higher altitude where the outside pressure is lower, but the temperature is the same. ien C increased, but the temperature stays the same. tolan A pressure. Bolloon C b. The balloon is placed in a hyperbaric chamber where the pressure is C. The temperature of the balloon changes from 5 to 40 °C at constant d. The balloon is warmed and then cooled to its initial temperature and the pressure remains the same. 3110 10) The structures and boiling points of cyclopentane and tetrahydrofuran are shown in the following figure. Explain why the boiling point of tetrahydrofuran is higher than that of cyclopentane. Boiling point 49 °C 65 C 11) Draw a cartoon model of the cell membrane. Incorporate the following components in your model and label them: a) Phospholipid bilayer b) Inside the cell (Cytosol)Explanation / Answer
a)
if P decreases, then V increases, due to PV = k ratio, choose C
b)
if P increases, then V must decrease, due to PV = k ratio, choose A
c)
If T increases, then V must increse, so choose C
d)
if T final = the sam eof original, P = same, then
P and T ratios ar eleft equal
V = must be the same, choose B
