Molly inflates a beach ball to a volume of 8 liters in her air conditioned house where the temperature is 19 °C. Later that day, Molly takes the beach ball to the beach with some friends. The temperature at the beach was 33 *C, and the air pressure at the beach is the same as it was at the house. What will happen to Molly's beach ball when she is at the beach? Apply CER by: 1. making a claim as to what will happen to the beach ball. 2. supporting it with evidence [provide a calculation]. 3. connecting your claim and evidence with reasoning [the name and concept of the gas law you applied to solve the problem /answer the question and why you chose to apply it or why it fits this situation].
ميز هذا السؤال The ethyl alcohol(Mw=46.06 g/mol) content of many juice produced in the United States is 4.05% (vol/vol).

7. Unknown Pressure P Fluid of interest (Gas in most cases)- Po Ambient Fluid (Atmospheric pressure in most cases) Reference Fluid Density p (Liquid, e.g. water or mercury) Gage Pressure AP - P-Po - rgh In a manometer, the pressure p inside the apparatus is given as p = pex + pgh, where pex(po) is the external pressure, p is the mass density of the liquid in the tube, g = 9.806 m/s² is the acceleration of free fall, and h is the difference in heights of the liquid in the two sides of the tube. (The quantity pgh is the hydrostatic pressure exerted by a column of liquid. i) Suppose the liquid in the manometer is Hg, Pex is 760 torr, and the open side is 10.0 cm higher than the side connected to the sample. What is the pressure of the sample? The mass density of Hg at 25°C is 13.55 g/cm³. (Assume 25°C.)
You may assume the pressure on the balloon stays constant at exactly 1atm . Be sure your answer has the correct number of significant digits.
Can you show me how to set up a problem to answer this question? A balloon is filled with air on a warm day. The volume of the filled balloon is 2.00 L and the density of the air within the balloon is 1.165 x 10-3 g/mL. The balloon is then cooled and it contracts to a volume of 1.89 L. What is the density (g/mL) of the air in the cooled balloon?
a) Learning units: Hospitals need compressed oxygen cylinders. Suppose you are given the choice of purchasing four oxygen cylinders: the red one (P = 2.0 atm, V = 34000 cm³), the blue one (P = 24 bar, V = 1.0 L), the green one (P = 22,000 Pa, V = 24 L), and a special yellow one with 1024 oxygen molecules. If they are the same the price, which cylinder should you purchase? Show your reasoning. Assume ideal gas behavior and the gases are at room temperature (25°C).
