GAS LAWS
Science should be taught as a verb as well as a noun. Performing science is a compelling as well as an effective way to learn. It is through the process of exploration, creation and invention that theories are applied, ideas are tested and knowledge is synthesized.
Much of what discussed in the paper is to have an understanding of gases in the atmosphere, factors that affect the properties of these gases and so the laws of gases which help to do so. Now why do we need to study these laws? Because gases compose our atmosphere. These are responsible for the process without which no one can survive i.e. breathing.
Atmosphere is a gaseous envelope surrounding the earth. It is made up of a combination of water

One of the most important things about gases is that, despite wide differences in chemical properties, all the gases more or less obey the gas laws. The gas laws deal with how gases behave with respect to pressure, temperature, volume and amount. This uniformity of physical behavior was of great interest with early scientists. It is one of the dogmas of scientists that the behavior of a material is a reflection of the particles that make up the substance. In other words, differences between solids, liquids and gases reflect the movement of the small particles that compose all matter. This assumption is part of the Kinetic Theory Of Gases (Kinetic is from the Greek word for motion). Historically, the description of the gas properties has been summarized by the mathematical equations describing the relationships between the gas volume, pressure and temperature. These equations, named after the scientist who first demonstrated their validity, have been labeled the gas laws. These gas laws are best understood within the framework described as the kinetic theory of gases:
Gases are composed of molecules.
These molecules are in constant motion. This is why gases mix to uniformity and fill all portions of the containment vessel.
Molecules of the gas collide frequently with each other and with the walls of the containment vessel.
Under ordinary circumstances, the distance between the gas molecules is far greater than the size of the individual
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.
The purpose of this experiment is to investigate some physical and chemical properties of gases and to use these properties to identify these gases when they are encountered.
Small pockets of the specific liquid, that contains trapped gas, that is then released to the
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.

In experiment 10, the class was asked to demonstrate the basics of gas laws in order to understand the peeled egg Erlenmeyer flask demonstration. This experiment helps demonstrate Boyle’s Law and Amontons’ law for the class to gain an understanding of related gas laws for our thermodynamic knowledge.
suspects that the gas comes from the ring of solid particles (5). If he is
Background: This lab shows an understanding the ideal gas law. This lab is about using the ideal gas law to find your data so the scientist find the moles of magnesium used in the experiment. The ideal gas law is a law is characterized by three things absolute pressure (P), volume (V), and absolute temperature (T). This relationship between them may be deduced from kinetic theory and is called the.
from an area of higher concentration to an area of lower concentration. Respiration is an example of diffusing gas molecules that takes places in the lungs. The oxygen we inhale is exchanged for carbon dioxide in tiny air sacs in the lungs called alveoli. When oxygen-depleted blood goes near the lungs, carbon dioxide diffuses into the alveoli where it is eventually removed through exhalation. At the same time, oxygen diffuses from the
When we put gas inside the balloon the gas was evenly spread out making sure that the pressure was constant. This follows the Kinetic Theory of Matter because it explains that the particles of a substance are in a constant motion.
_The tank is compressing the helium into a denser state but when it is put in the balloons it expands and takes up more space. __________________________________________________________________________
The atmosphere is a complex fluid system outside Earth from a variety of gases and suspended solids consisting of participation in life activities are under long-term development and formation.
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.
Answer: A Gas Transfer Vacuum Pump will move the molecules out of the system so that the vacuum environment is formed.
