Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.

Mr Luda wants to understand further about a newly created gas. The gas is initiallyat a pressure of 90 kPa, volume of 1.258 m3 and temperature of 10°C (State 1).The gas undergoes a 3-step process in which it is first compressed isothermally toa pressure of 400 kPa and volume of 0.283 m3 (State 2), then expanded at constantpressure back to its original volume (State 3). Finally, the gas is returned to itsoriginal State 1 by cooling at constant volume.a) Sketch the cycle of this system on a P – V diagram.b) Calculate the work done (in kJ) for each process step.c) Determine the total work done for the three-process cycle.d) State whether the work done is on or by the system.

An airtight dispenser for drinking water is 25 cm × 10 cm in horizontal dimensions and 20 cm tall. It has a tap of negligible volume that opens at the level of the bottom of the dispenser. Initially, it contains water to alevel 3.0 cm from the top and air at the ambient pressure, 1.00 atm, from there to the top. When the tap is opened, water will flow out until the gauge pressure at the bottom of the dispenser, and thus at the opening of the tap, is 0. What volume of water flows out? Assume the temperature is constant, the dispenser is perfectly rigid, and the water has a constant density of 1000 kg/m3

As2...Suppose that we could increase the atmospheric pressure on the surface of Mars to 0.2 bar, by vaporizing the polar caps and subsurface ice. This atmosphere would then likely decrease over time, as a result of several processes, such as escape into space, and erosion by the solar wind. How would the surface pressure decrease as a function of time? How much time would it take until the pressure is only 0.1 bar?
