Ideal Gas Law Many gases can be modeled by the Ideal Gas Law, PV = nRT, which relates the temperature (T, measured in Kelvin (K)), pressure (P, measured in Pascals (Pa)), and volume (V, measured in m3) of a gas. Assume that the quantity of gas in question is n = 1 mole (mol). The gas constant has a value of R = 8.3 m3-Pa/mol-K.
a. Consider T to be the dependent variable and plot several level curves (called isotherms) of the temperature surface in the region 0 ≤ P ≤ 100,000 and 0 ≤ V ≤ 0.5.
b. Consider P to be the dependent variable and plot several level curves (called isobars) of the pressure surface in the region 0 ≤ T ≤ 900 and 0 < V ≤ 0.5.
c. Consider V to be the dependent variable and plot several level curves of the volume surface in the region 0 ≤ T ≤ 900 and 0 < P ≤ 100,000.

- The Beer-Lambert Law As sunlight passes through the waters of lakes and oceans, the light is absorbed, and the deeper it penetrates, the more its intensity diminishes. The light intensity I at depth x is given by the Beer-Lambert Law: I=I0ekx where I0 is the light intensity at the surface and k is a constant that depends on the murkiness of the water see page 402. A biologist uses a photometer to investigate light penetration in a northern lake, obtaining the data in the table. Light intensity decreases exponentially with depth. Use a graphing calculator to find an exponential function of the form given by the Beer-Lambert Law to model these data. What is the light intensity I0 at the surface on this day, and what is the murkiness constant k for this lake? Hint: If your calculator gives you a function of the form I=abx, convert this to the form you want using the identities bx=eln(bx)=exlnb. See Example 1b. Make a scatter plot of the data, and graph the function that you found in part a on your scatter plot. If the light intensity drops below 0.15 lumen lm, a certain species of algae cant survive because photosynthesis is impossible. Use your model from part a to determine the depth below which there is insufficient light to support this algae.

A mole of water, for example, is about 18 grams, or just over half an ounce in your kitchen. Chemists often use the mole as the measure of the amount of a chemical compound. A mole of carbon dioxide has a fixed mass, but the volume V that it occupies depends on pressure p and temperature T; greater pressure tends to compress the gas into a smaller volume, whereas increasing temperature tends to make the gas expand into a larger volume. If we measure the pressure in atmospheres 1 atm is the pressure exerted by the atmosphere at sea level, the temperature in kelvins, and the volume in liters, then the relationship is given by the ideal gas law: pV=0.082T. a. Solve the ideal gas law for the volume V. b. What is the volume of 1 mole of carbon dioxide under 3 atm of pressure at a temperature of 300 kelvins? c. Solve the ideal gas law for pressure. d. What is the pressure on 1 mole of carbon dioxide if it occupies a volume of 0.4 liter at a temperature of 350 kelvins? e. Solve the ideal gas law for temperature. f. At what temperature will 1 mole of carbon dioxide occupy a volume of 2 liters under a pressure of 0.3 atm?arrow_forwardRelativistic Length A rocket ship travelling near the speed of light appears to a stationary observer to shorten with speed. A rocket ship with a length of 200 meters will appear to a stationary observer to have a length of 2001-r2 meters, where r is the ratio of the velocity of the ship to the speed of light. What is the apparent length of the rocket ship if it is travelling at a speed that is 99% of the speed of light?arrow_forward
