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.

5. A copper calorimeter can with mass 0.446 kg contains 0.0950 kg of ice. The system is initially at 0.0 C. (a) If 0.0350 kg of steam at 100.09C and 1.00 atm pressure is added to the can, what is the final temperature of the calorimeter can and its contents? (b) At the final temperature, how many kilograms are there of ice, how many of liquid water, and how many of steam? 6.

V. W. Th To %3D Room temperature T = 293 K V V. Vp The gas volume changes from Vp to Va at constant temperature T. The cartoon on the right shows a piston of gas undergoing this compression while submerged in a container of room temperature water, which acts as a reservoir. The initial state of this process is a piston containing 2 moles of a monatomic gas at Tc = 293 K (room temperature water) and volume V = a 1.0 m. The gas is compressed until V, = 0.2 m. During the compression, the heat bath of room temperature water maintains the temperature of the gas at T 293 K. Calculate the work done in joules by the gas during this process. Do not include units in your answer. Be careful to use the standard sign convention for work done by the gas. Write your numerical answer in normal form as described above in the instructions to this worksheet.
Mr Zul operates a hot plate. He places a closed, rigid container of volume 0.5 m3on the hot plate. Initially, the container holds a saturated mixture with quality ofvapour of 0.5, at a pressure of 100 kPa. After heating, the pressure in the containerincreases to 150 kPa.a) Calculate the mass of vapour at the initial and final states (in kg).b) If heating is allowed to continue, find the pressure (in kPa) when thecontainer holds only saturated vapour.c) Sketch the T – v diagram for this system.
