400.0 ml of a gas are under pressure of 80.0 kpa what would the volume of the gas be at a pressure of 100.0 kpa

Ber [7]

Answer:

The final volume is 320 mL at pressure of 100 kPa.

Step-by-step explanation:

Boyle's law gives the relation between volume and pressure of a gas. It states that at constant temperature, volume is inversely proportional to its pressure such that,

$V\propto \dfrac{1}{P}\\\\P_1V_1=P_2V_2$

Let

$V_1=40\ mL\\\\P_1=80\ kPa\\\\P_2=100\ kPa$

We need to find $V_2$ . Using above equation, we get :

$V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{400\times 80\times 10^3}{100\times 10^3}\\\\V_2=320\ mL$

So, the final volume is 320 mL at pressure of 100 kPa.

Which equation has the solution x = 3?

dybincka [34]

Answer:

2x + 4 = 10 = x =3

Step-by-step explanation:

09 - 31 = 0 (the variable x is not present in the given system)

0 +5=6 (the variable x is not present in the given system)

2x + 4 = 10 = x = 3

09-1=4 (the variable x is not present in the given system)

51 - 7 = 1 (the variable x is not present in the given system)

3x + 1 = 9 = x = 8/3
