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.

A 300 ml sample of dry oxygen at STP ( standard temperature and pressure ) is transferred to a container over water at 19 deg C and 750 mmHg. What is the new volume of the oxygen?
The following experiment is carried out: 10 moles of a gas are placed in a piston equipped with acylinder device so we can increase or reduce the pressure upon compression or expansion. Duringall the experimental steps, we will keep the experimental setup at a constant temperature of T =60°C. The initial pressure is 0.2 bar and the next steps are followed out:Step 1: The gas is compressed to P = 0.7 bar, where we see that condensation begins.Step 2: At the end of the condensation, the volume is 0.80 L. Equipment readings tell us that 495kJ of heat was removed during the condensation.Step 3: The liquid is then compressed to P = 13.5 bar and V = 0.77 L, where we see that solidsbegin to form.Step 4: At the end of the conversion of all the liquid into solid, the volume is 0.72 L and wemeasured 25 kJ of heat removed during this step. Use the above experimental observations to estimate each of the following properties for this compound. A) The isothermal compressibility of the liquid phaseB)…
