Airbags are safety features that are designed to save passengers from harm in a head-on collision. Airbags react within milliseconds of a crash, and the folded nylon bag quickly becomes inflated with nitrogen gas. The inflated airbag has the role of being a cushion for passengers and prevents them from hitting into the steering column and dashboard, which can cause painful injuries for passengers. Airbags were invented by John Hetrick in 1953 after Hetrick, his wife and young daughter got

Boyle's Law Examples in Real Life Boyle's Law Explained In 1662, Robert Boyle discovered that when held at a constant temperature, the volume and pressure of a gas are inversely proportionate. Put simply, when the volume goes up, pressure drops, and vice versa. The mathematic equation is equally as simple: PV=K where P=Pressure, V=Volume, and K is simply a constant. This has become a basic principle in chemistry, now called "Boyle's law" and is included as a special case into the more general

of ability to do their jobs too which may cause them to get unemployment. There are many reasons why students like cheating, but according to some researchers, there are top three reasons why students are likely to cheat: lack of effort, external pressures and opportunity. To begin with, cheating is likely to be occurring on students who are lack of effort in their studying. Students who did not attend class or did not study are considered to be lack of effort students. Those students are rare

to the physical. In this the material we used was, a sip-lock plastic bag, a large plastic beaker, thermometry, dry ice, water, and butane lighter. Introduction In this lab, the experiment focused on the relationship between the temperature and pressure of an ideal gas that was dry ice inside the closed container. Therefore, the volume remains constant because the ideal gas was in a closed container. Experiment Procedure First, all the materials were collected. After collecting all the materials

aircraft. Several laws affect air travel including Boyle’s law, Henry’s law, Dalton’s law and Graham’s Law. Boyle’s law is relevant as it explains how pressure changes allow the gas to expand (Monroney, 2013). Dalton’s law transfers oxygen molecules from a person’s lungs to their bloodstream depending on the pressure gradient. Henry’s Law relates to the pressure of a gas over liquid (solubility). Within humans physiology the three physiological zones within the atmosphere are utilised to control conditions

ball to actually curve in the air is a difference in the pressures on either side of the soccer ball. On the left side of this soccer ball, the air is moving faster, than the right side, relative to the center of the ball. This causes a lower pressure to develop on the left side of the ball, while on the right side there is a higher pressure because the air flow is moving slower relative to the center of the ball. This difference in air pressure causes the ball to curve to the left during its flight

Even though the number of molecules in 1 atm of gas at constant pressure and temperature is identical, the number of atoms in the gas at STP can vary depending on the gas. How many atoms are there in one mole of methane (CH4) 1 mole of Methane CH4 = (6.022 x 1023 atoms/mole) = 6.022x1023 atoms of Methane in one mole 6. In this experiment, the pressure (P) was 1 atm, the temperature (T) was 295 K, the volume (V) was 0.150 L, and the number of moles (n)was
