Question
Chapter 59.3, Problem 2EQ
Summary Introduction
To determine: The purpose of increasing the level of carbon dioxide in only half of the chambers and not in all chambers during the experiment.
Introduction: Peter Stiling and Bert Drake performed various experiments to increase the level of carbon dioxide around the patches of forest in Kennedy Space Center in Florida. They carried out these experiments for observing the response of forest ecosystem to elevated level of carbon dioxide.

Charles' Law
Change the simulation to "Charles' Law" by clicking the tab at the top of the screen it will be shown in white. You should see
the picture below on your screen.
1. Which one of the three variables: Pressure, Volume or Temperature cannot be changed in Charles' Law? This varlable
is considered a constant.
1. a. Using the Temperature controls, increase the temperature of the gas. What changes do you observe in the behavlor
of the particles of the gas while the temperature is increased?
b. Continue to increase the temperature value until T, = 44K. Using the equation for Charles' law, calculate the volume of
the gas at this increased temperature. Check your final answer for part b by clicking the calculate button next to V2:
c. Based on the final value calculated in part b) is Charles' law considered a direct or an indirect relationship between the
variables? Explain your cholce with reasoning.

- What strategy would best measure the influence of temperature and PTU on oxygen consumption? OI will compare how the weights of the control mouse (not treated with PTU) and the experimental mouse (treated with PTU) change with temperature. I will compare the oxygen production of a control mouse (not treated with PTU) and an experimental mouse (treated with PTU) I will compare the normalized oxygen consumption at different temperatures for a control mouse (not treated with PTU) and an experimental mouse (treated with PTU)arrow_forwardInformation on a variety of variables were collected prior to beginning the exercise. In what way do you believe temperature, barometric pressure, and relative humidity may play a role in VO2 values?arrow_forward13. There are several ways to measure cellular respiration experimentally. For example, CO2 and O2 gas sensors measure changes over time in the concentration of carbon dioxide or oxygen, respectively. Design two experiments to test the effects of changing two different variables or conditions (one per experiment) on the respiration of research organism of your choice.arrow_forward
