The Gas Law : Law And Gay Lussac 's Law

Oxygen is drawn into the lungs by a process called inhalation, (breathing in), which occurs when the diaphragm and intercostal muscles are contracted which causes the lungs to expand, giving a larger volume and therefore causing a lower pressure differential between the lungs, alveolar pressure, and the outside atmosphere. This inverse relationship between volume and pressure is called Boyle’s law. (Tortora & Derrickson, 2011)

10) The tape was used to measure gas accumulation in the balloon after 1minute. Measurement and qualitative observations were recorded.

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. _________________________________

The bronchial tubes increase in length and diameter during inhalation. Bronchial tubes decrease in length and diameter during exhalation. Poiseuille’s law can be applied to the lungs when the bronchial tubes become constricted due to an increase in mucus production and can decrease in size. When the bronchial tubes decrease in size and the patient is breathing, it is going to take more pressure to move the air into the swelled bronchi. If the radius of a patient’s bronchial tubes increased by sixteen percent, the pressure to move oxygen into the lungs would double. Therefore, a patient with bronchial smooth muscle constriction of sixteen percent would have to double their driving pressure to keep a constant flow rate. If swelling occurs and the patient does not increase their pressure, the amount of oxygen they are getting to their lungs will decrease. Respiratory therapists can see this taking place in patients with asthma that have excess mucus secretions.

The presence of fluid in the alveolar space could potentially cause the lung capacity to be effected as well.

Scuba diving is a method of underwater diving in which a diver utilises a Self-Contained Underwater Breathing apparatus (Scuba) to breathe under water. There are three main gas laws that are pertinent to scuba diving. These are Boyle’s Law, Dalton’s Law and Henry’s Law. Throughout this presentation we will examine how gas laws relate to the diving industry and how innovative technology could transform the future of diving.

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.

A sample of gas is trapped in a sealed container, which has a movable lid. Moving the lid up or down will change the volume inside the container. You will use an attached manometer to measure the pressure inside the container.

To use the ideal gas law, the atmospheric pressure was adjusted for due to the lower pressure in the buret when compared to the outer atmospheric pressure. This unequalization of pressures, although corrected, may still be slightly off, thus potentially causing later calculation error when using the ideal gas law to solve for the moles of CO2.

The purpose of this lab was to determine the effect of temperature on the volume of gas when the pressure is consistent and to verify Charles’ Law. The data from the experiment reveals that as temperature increases, so does volume. This also indicates that as temperature decreases, the volume decreases as well.

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

The law of thermodynamics in can predict the direction of chemical reactions and changes in substances

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.

Where he excluded water vapor from his apparatus and used dry gases. He had concluded that equal volumes of all gases expanded equally with the same increase of temperature. Gay Lussac’s laws stated that combining volume state, gases react together to form other gases. His laws dealt with volumes, pressures and temperatures. Another experiment Joseph Louis Gay- Lussac conducted was with a hydrogen balloon.

During decent and while divers are on the bottom the diver is continually absorbing nitrogen into the tissues until the pressure in the tissues is equivalent to the external pressure of the surroundings. This is when a person’s tissues are saturated and cannot absorb any more nitrogen. When the diver ascends slowly the nitrogen
