Question

If temperature is held constant and we decrease the volume from a hypothetical 105 mL to 65 mL our pressure
would increase or decrease) from 11.5 atm to what atmospheric pressure?

Answer 1

Answer:

18.6 atm

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new pressure

$P_2 = \frac{P_1V_1}{V_2}$

We have

$P_2 = \frac{105 \times 11.5}{65} = \frac{1207.5}{65} \\ = 18.5769$

We have the final answer as

18.6 atm

Hope this helps you
