Chemistry Chapter 10 Notes

A sample of gas at 6.0 atm and 5.0ºC increases in temperature to 35ºC. If the volume is unchanged, what is the new pressure?

I would guess that the surface area has been decreased and the diffusion distance for gas

B. How does this graph illustrate Boyle’s law? As more pressure is added the volume decreases and the graph shows this because it is decreasing as well. _________________________________

5) List the three common states of matter in order of highest potential to lowest.

Poiseuille’s law states the volume in a tube is directly proportional to pressure difference between both ends of the tube and inversely related to the length. Poiseuille’s law was discovered by Jean Louis Marie Poiseuille in 1840 (Poiseuille’s). Jean Louis used his experiments to find the smooth, laminar flow in circular tubing (Jean-Louis). His findings can be described as the flow of blood through the body and bronchial smooth muscle.

Think about the gas laws we are studying. Boyle’s law tells us that pressure and volume are inversely proportional. Charles’ law states that volume and temperature are directly proportional. We also know that pressure and temperature are directly proportional. Discuss at least one instance in your personal experience where you have seen one or more of these laws in action.

3. Use the buttons on the heater to change the temperature of the gas. The volume of the gas will change in response to the temperature change. Notice that the container is sealed and the pressure is adjusted so that it remains constant. Measure and record the volume and temperature of the contained gas.

Temperature scales are also used in an attempt to make the concept of measuring pain more relatable. Across the world, temperature is measured in degrees Celsius. At zero, water freezes and, at one hundred, water boils. Despite Celsius being the global standard, the Fahrenheit scale was developed decades earlier. Daniel Gabriel Fahrenheit based his temperature scale on two marks: on the lower end, the point where a mixture of salt and water would cease to exist as a liquid, and, on the upper end, a measure of normal body temperature. In an effort to add more confusion to the two standards, Lord Kelvin introduced the idea of an “absolute zero.” Absolute zero is the point where molecules and atoms are supposed to be essentially motionless. Despite this, research has showed that the motion doesn’t really stop. As Biss says, “…absolute is not absolute.” She finds that comforting, but not quite enough.

So an increase in pressure would cause an increase in the equilibrium yield of COCl2

The pressure of a gas sample increases for a decrease in volume and decreases for an increase in volume.

In Measuring and Understanding Density, several experiments were performed to find density of regularly shaped objects, irregularly shaped objects, liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus its temperature. Key measurements and formulae were also used to determine densities of metal and plastic objects as well as irregularly shaped rocks. It is possible to find the density of an object (be it liquid, gas or

The water in the jar encounters higher pressure than the water in the pan, so the boiling temperature of the water in the jar is higher than that of the water in the pan. Thus, the water in the pan will boil first, and the water in the jar will not boil.

In this experiment, we will collect data from the sample and use the Ideal Gas Law:

Robert Boyle, a philosopher and theologian, studied the properties of gases in the 17th century. He noticed that gases behave similarly to springs; when compressed or expanded, they tend to ‘spring’ back to their original volume. He published his findings in 1662 in a monograph entitled The Spring of the Air and Its Effects. You will make observations similar to those of Robert Boyle and learn about the relationship between the pressure and volume of an ideal gas.

The theory of Corresponding States proposes that all gases will exhibit the same behaviour, e.g. z-factor, when viewed in terms of reduced pressure, reduced volume, and reduced temperature.
