At a pressure 41 kPa, the gas in a cylinder has a volume of 16 liters. Assuming temperature remains the same, if the volume of t
DiKsa [7]
If temperature (T) and amount of gas (n) remain constant, but pressure (P) and volume (V) change, then the ideal gas law: PV = nRT becomes
P1V1 = P2V2 --> (41)(16) = P2 (4)
--> P2 (4) = 656
P2 = 656/4 = 164 kPa

A jewelry box has a length that is 2 inches longer than the width and a height that is 1 inch smaller than the width. the volume
maxonik [38]
Given that a <span>jewelry box has a length that is 2 inches longer than the width and a height that is 1 inch smaller than the width.

Let the width of the box be w, then the length of the box is given by l = w + 2 and the height of the box is given by h = w - 1.

The volume of a box is given by

V=l\times w\times h \\  \\ =w(w+2)(w-1) \\  \\ =w(w^2+w-2)=w^3+w^2-2w

Given that the volume of the box is 140 cubic inches. Thus

w^3+w^2-2w=140

Thus, the width of the jewelry box is obtained as follows

w^3+w^2-2w=140 \\  \\ \Rightarrow w^3+w^2-2w-140=0 \\  \\ \Rightarrow(w-5)(w^2+6w+28)=0 \\  \\ \Rightarrow w=5

Therefore, the width of the jewelry box is 5 inches.

*Note that w^2+6w+28=0 gives complex roots, so we did not use it.
