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 cylinder is fitted with a freely movable piston of area 1.20e-2m^2 and negligible mass. The cylinder below the piston is filled with a gas. At state 1 the gas has volume 1.50e-3m^3, pressure 1.02e5Pa, and the cylinder is in contact with a water bath at a temperature of 0.0C. The gas is then taken through the following four step process. - A 2.50kg metal block is placed on top of the piston, compressing the gas to state 2, with the gas still at 0.0 C. - The cylinder is then brought in contact with a boiling water bath, raising the gas temperature to 100C at state 3. - The metal block is removed and the gas expands to state 4 still at 100C. - Finally, the cylinder is again placed in contact with the water bath at 0C, returning the system to state 1. a) Determine the pressure of the gas in state 2. b) Determine the volume of the gas in state 2. C) Determine the volume of the gas in state 4. Answer all parts, ABC
