Question

#2: A gas at unknown pressure and a volume of 66 cm has its pressure changed to 150 kPa. The new volume

Answer 1

Answer:

377 kPa

Explanation:

The original 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 original pressure

$P_1 = \frac{P_2V_2}{V_1}$

150 kPa = 150,000 Pa

We have

$P_1 = \frac{150000 \times 166}{66} = \frac{24900000}{66} \\ = 377272.72...$

We have the final answer as

377 kPa

Hope this helps you
