The amount of carbon dioxide produced can be determined by measuring pressure because for a gas, the pressure (P) is related to the number of moles of the gas (n) through the ideal gas law: PV =nRT	The amount of carbon dioxide produced can be determined by measuring pressure because for a gas, the pressure (P) is related to the number of moles of the gas (n) through the ideal gas law: PV =nRT Not at all	The amount of carbon dioxide produced can be determined by measuring pressure because for a gas, the pressure (P) is related to the number of moles of the gas (n) through the ideal gas law: PV =nRT A little	The amount of carbon dioxide produced can be determined by measuring pressure because for a gas, the pressure (P) is related to the number of moles of the gas (n) through the ideal gas law: PV =nRT Mostly	The amount of carbon dioxide produced can be determined by measuring pressure because for a gas, the pressure (P) is related to the number of moles of the gas (n) through the ideal gas law: PV =nRT Very
Light is a spectrum characterized by its wavelength, and interacts with materials differently. In this experiment, yellow light has a wavelength that interacts with the silver nanoparticles of a specific size, allowing us to recognize the optimal nanoparticle solution when it turns yellow.

Please offer your explanation to the following questions:

Question Title

* 4. The result of your experiment should suggest that silver nanoparticles less than 20 nm in diameter are more effective in killing yeast cells than silver powder, with diameters in the millimeter range. Provide one reason for why nanoscale silver is more effective:

Question Title

* 5. Which parameter of the ideal gas law (PV= nRT) does the height of the manometer tube represent when you collect your data in this experiment?

Question Title

* 6. In this experiment, we approximated that the yeast cells produce carbon dioxide at a constant rate. List at least two ways in which you can increase the cells’ carbon dioxide production rate:

Question Title

* 7. You just discovered a drug that kills cancer cells, but this drug by itself can’t penetrate the membrane to get inside the cell, where the drug can be effective. Using the lesson you learned in this experiment, suggest one method by which you can help the drug penetrate the cell membrane.

Question Title

* 8. Identify any concepts that you might have better understood after performing this activity:

None

Cell Membrane

Ideal Gas Law

Nanoparticles

Antimicrobials

Other (please specify)
