Question

A certain gas has a volume of 600 cm3. What is its volume when the pressure is tripled?

Answer 1

Using Boyle law we can conclude:

$P_1V_1=P_2V_2$

Where:

P1 = Initial pressure

P2 = Final pressure

V1 = Initial volume

V2 = Final volume

Since:

P2 = 3P1:

$\begin{gathered} P_1V_1=(3P_1)V_2 \\ V_1=600 \\ so: \\ V_2=\frac{600}{3} \\ V_2=200cm^3 \end{gathered}$

Answer:

200 cm^3
