CHEM-120 Unit 4 Lab: OL Lab 8: Acids and Bases
CHEM120 OL, Week 4 Lab
Observations: Record three observations from the simulation.
The temperature scale is arbitrary. Change in gas physical property is linked to temperature change. Ideal Gas law states that volume is proportional to temperature.
Answer the questions below:
1. If the pressure of a fixed volume of gas decreased in a sealed container, what variable would you think changed? Did this variable increase or decrease?
Pressure of gas is inversely related to volume. Therefore, if the pressure is decreased that means volume is increased.
2. Why is it important to convert into units of Kelvin before using the Ideal gas law?
The Kelvin scale is proportional to the Kinetic energy of the particles, and the pressure and volume of gas depends on the kinetic energy of the particles.
3. Using what you learned in this simulation, explain why compressed gas cylinders, such as those found in the hospital, typically contain a warning to not leave in sunlight or expose to heat.
The compressed gas cylinders mean there is a high pressure inside of it and exposing it to heat will raise the temperature causing the pressure to increase more and may lead to an explosion.
4. Reflection: Consider what you learned from this simulation. Reflect on three to four key concepts that you learned in this lab exercise. How could the lessons learned in this virtual lab related to a real world situation in the community/world or your future career? Be specific in your answer (this should require 5-10 sentences).
In this week’s lab simulation on Ideal gas law I have learned how temperature, pressure and volume affects each other. These three variables affect how a gas reacts. Pressure of gas is inversely related to volume.
Therefore, if the pressure is decreased that means volume is increased. If temperature is raised pressure will be raised as well because of the increased kinetic energy which causes the gas particles to collide to the wall’s container which then increases the pressure. Absolute zero cannot be realistically achieved in a lab setting.
