Question

What is the original pressure of a bike tire if the current pressure is 160atm and the volume changed from 1000mL to 700mL. Please show all work including the equation you used.

Answer 1

For this question, we can use Boyle's Law formula to answer, since this law is an experimental gas law that states that pressure and volume have an inverse relationship. The formula is:

P1V1 = P2V2

We have:

P1 = ?

V1 = 1000 mL

P2 = 160 atm

V2 = 700 mL

Now we add these values into the formula:

P1*1000 = 160*700

P1 = 112 atm
