The volume of 400 mL of chlorine gas at 400 mm Hg is decreased to 200 mL at constant temperature. What is the new gas pressure?
rusak2 [61]

A. Let us first assume that the gas acts like an ideal gas so that we can use the ideal gas equation:

PV = nRT

where P is pressure, V is volume, n is number of moles, R is universal gas constant and T is absolute temperature

In this case, let us assume that nRT = constant so that:

P1V1 = P2V2

400 mm Hg * 400 mL = P2 * 200 mL

P2 = 800 mm Hg

 

<span>B. The collision of gas with the walls of the container produces Pressure.</span>

Answer:

25 ft^2

Step-by-step explanation:

In direct variation, if y varies directly with x, then the equation has the form

y = kx,

where k is the constant of proportionality. y is proportional to x.

Let's call the area y and the distance x.

Here, the area varies with the square of the distance, so the equation has the form

y = kx^2

Here, y is proportional to the square of x.

We can find the value of k by using the given information.

y = kx^2

When x = 20 ft, y = 16 ft^2.

16 = k(20^2)

k = 16/400

k = 1/25

The equation of the relation is:

y = (1/25)x^2

Now we use the equation we found to answer the question.

What is y (the area) when x (the distance) is 25 ft?

y = (1/25)x^2

y = (1/25)(25^2)

y = 25

Answer: 25 ft^2
