General Aim
Verification of Boyle’s law by using gas law simulation lab.
Method of Boyle’s Experiment
J- shaped tube method
Learning Objectives (ILOs) of Boyle's law simulation
By the end of the Boyle's law simulation, student will be able to:
Explain the relation between the pressure exerted on an ideal gas and the volume it occupies at constant temperature by using Boyle's law lab experiment.
Set up an experiment (Boyle's experiment) to study the pressure-volume relation for an ideal gas.
Learn how to use gas law simulator
Theoretical Background / Context
- Now consider the J-tube shown in Figure (1). If mercury is poured into this tube from its open end, a certain quantity of air is trapped in the closed tube.
Fig 1. Fig 2.
- If we raise the open-end tube, the pressure on the trapped air increases by the amount made by the excess mercury in the open tube.
- Now if we plot a graphical relation between the 1/Vf on the vertical axis vs pf on the horizontal axis, we should get a straight line as shown in Figure (2). Hence, Boyle’s law is verified.
Principle Work of Gas Law Simulation Lab
In Boyle's law virtual lab, study the change in volume occupied by a gas when the pressure exerted on it changes at constant temperature..
“With the onset of the COVID-19 pandemic, we found ourselves in a situation that forced us to act quickly to find the best solution available to provide our students with a quality molecular genetics laboratory experience.”
'' Although there are now several vendors offering virtual reality software for physics labs, there is only one that offers a realistic, I feel like I’m in a real lab, solution: PraxiLabs.''
" PraxiLabs offered my students a chance to actively engage with the material. Instead of watching videos on a topic, they could virtually complete labs and realize the practical applications of class topics. This is a quality alternative to in-person labs."
"Great user experience and impressive interaction, I am very pleased to have tried the simulations and will continue to do so."
