Question

The pressure on 2.50L of N2O changes from 1 atm to 0.4 atm. What is the new volume?

Answer 1

6.25 L

Step-by-step explanation:

Boyle's law says Pressure and volume are inversely related. One goes up and other goes down (vice versa).

P1 V1 = P2 V2

(2.5) (1) = (0.4) (x)

x= 6.25 L

The answer should make sense because your pressure went from high to low which means your volume should opposite, from low to high, and that's what we see.
