Question from leria, a student:
In Boyle's law, the pressure of gas varies inversely with the volume of the gas. A volume of 11.2 liters of air exerts a pressure of 2.0 atmospheres.
determine the constant of variation and write an equation the models the relationship between the pressure of the gas P and its volume, V. Use the equation to predict the volume of air necessary to exert a pressure of 0.25 atmospheres.
I wanted to use a ration to solve this problem.
11.2 / 2.0 = x / 0.25
2X = 2.8
2.8 / 2 = 1.4
Will it take 1.4 volume of air to exert a pressure of 0.25.
I know you like for the students to try to solve it. However I'm not
sure if I'm on the correct track. Please help. Thank you.
