Answer: -2
Y = x(x+3)
Y = (-2)((-2)+3) * Distribute*
Y = 4 - 6
Y = -2
Given:
radius of a cylindrical construction pipe is 3 ft
lenghtis 25ft long
Required:
what is it’s volume
Explanation:
volume of cylinder:
Required answer:
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>
