As shown in the diagram, the state of helium gas is changed in such a way that its PV graph is a straight line segment with volume Vo increases to yVo and pressure Po increases to xPo where x and y are arbitrary constants. During this process the total heat transferred to the gas is equal to the heat necessary to double the absolute temperature of the gas at constant volume. What is the maximum ratio for the volume increase? xP, P. Vo
In a reciprocating air compressor, high pressure air in the cylinder pushes the piston against the external load and expand to a lower pressure.

You will start by getting used to the idea of the linear mass density by relating it to concepts you are already familiar with: the mass and the (volume mass) density.* First, you have a column of pure water that has a density PH₂0 = 1 g/cc. The water column is in a cylinder. The column has cross-sectional area 31 cm² and height 75 cm before salt is added. The linear mass density has two different definitions. One is going up in dimensionality, that is from the volume mass density p to the linear mass density λ = PA where A is the cross-sectional area of the object. The other is going down in dimensionality, that is from the mass down to the linear mass density λ = M H where H is the height of the column in our case. You will use both of these below: (a) What is the linear mass density of the water column? ÅH20 = (b) What is the mass of the water? M = Let's now try this after adding salt to the water. When we do, the column's height rises to a level 78 cm, and we measure its salinity…
