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.

The area of a rectangular gymnasium is (5x+5x) square feet. If it is 5x feet wide, what is the length, in feet?
Amiraneli [1.4K]

Answer:

Step-by-step explanation:

Area = L x W      gym area is (5x + 5x) ft²      if   W = 5x      Find the L

Area = L x W       divide both sides by W

Area/W  = (L x W) / W

Area/W  =  L  =  Area/W

    L = Area/W

       =  (5x + 5x) / (5x)

       =  5x( 1 + 1) / 5x

       =  5x(2) / 5x                      the 5x's cancel each other  5x/5x = 1

       =   2 ft          I got 2.  I suspect the 12 was a typo and should have been 2
