At constant temperature, the pressure of a sample of gas is inversely proportional to its volume. i have some oxygen in a 2.28 liter container with a pressure of 5 kpa. if i move all of it to a 5.7 liter container at the same temperature, what will the new pressure be in kpa?

The new pressure is 2 Kpa

Solution:

At constant temperature, the pressure of a sample of gas is inversely proportional to its volume

Therefore,

Let "p" be the pressure of sample gas

Let "v" be the volume

Then we get,

Where, "k" is the constant of proportionality

I have some oxygen in a 2.28 liter container with a pressure of 5 kPa

Substitute v = 2.28 and p = 5 in eqn 1

I move all of it to a 5.7 liter container at the same temperature

Substitute k = 11.4 and v = 5.7 in eqn 1

Thus new pressure is 2 kPa

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
