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.

Question

Problem 7 Can of Gas
A can with volume V has N molecules of nitrogen contained inside. A plug at the top has mass m and
cross-sectional area A. The plug can withstand a force of 2mg before it would pop loose. The pressure
of the outside air is Po. (a) Draw a free-body diagram of the plug. (b) Assuming the outside air and gas
inside the container have the same temperature, at what outdoor temperature would the plug pop loose?

Pre-lab 8: Cold Engine The experimental setup for this week's lab consists of a syringe connected to a metal can (reservoir), a cold bath (water - ice mixture) and a "hot" bath (water at room temperature). A schematics of the syringe - reservoir system is shown below. Plunger of mass m Filled with gas (air) Syringe of volume Vcor VH - Volume Vo includes tube + Metal can -Metal can submerged in water of temperature Тс or TH. Tube Stopper Figure 1: Schematic of the syringe - reservoir system. The syringe is essentially a glass cylinder fitted with a movable piston (plunger). The markings on the syringe indicate the volume of gas in the syringe, but do not include the additional, unknown volume, Vo, in the gas can and tubing.
A child takes a helium balloon on a plane from Denver (with an air pressure of 0.83 atm) on a cool day when the temperature is 20.0oC to Boston (at sea level, with an air pressure of 1.0 atm) where the temperature is 5.0oC. Assume that no gas escapes from the balloon during the flight. What is the volume of the balloon in Boston, relative to its size in Denver? Group of answer choices The volume in Boston is 0.79 times the volume in Denver. The volume in Boston is 0.20 times the volume in Denver. The volume in Boston is 0.87 times the volume in Denver The volume in Boston is 1.3 times the volume in Denver. The volume in Boston is the same as the volume in Denver.

A Midwest Cooperative needs to store 15 750 gallons of a liquid chemical. They are considering two possible containers, a hollow cylinder or a hollow sphere. The wall of the sphere will need to be 6 in. thick and the wall, top and bottom of the cylinder are each 6 in. thick. Due to space limitations the height of the cylinder must be 26.0 ft. (a)What will be the outside diameter of the cylinder required to hold the liquid chemical? (b)What will be the outside diameter of the sphere? (c)Assume the containers are made of aluminum, which container uses the most material?
