affect air pressure. In the experiment, the basketball was measured in four different temperatures. Therefore, the basketball was dropped at a certain height. The results were as the temperature increases, the bounce of the basketball increases. If you ever played a sport, or drove a car, you probably never thought if on a cold day would it ruin a ball, or flatten your tire. Maybe on a hot day, the temperature can affect how high it would bounce. How does temperature affect air pressure?…

kept constant, pressure (P) and volume (V) have an inversely proportional relationship. Boyle’s constant (B) can be expressed by V=B/Pwhere volume is (in this lab) cm^3 and pressure is in atm. Charles’ Law states that when pressure is held constant, temperature and volume are directly proportional. Charles’ constant (C ) can be expressed by V=CTwhere volume is in cm^3 and temperature is in Kelvin. Gay-Lussac’s Law states that when volume is held constant, temperature and pressure are…

volume of a mole of H_(2(g)) is 22.4 L, it supports Avogadro’s law that one mole of an ideal gas occupies 22.4 L at STP. At the same time, it indicates that a direct relationship exists between volume and the number of moles of gas as temperature and pressure stays constant. One real world application of the importance of this problem is demonstrated when a helium balloon is lighter than an identical balloon filled with air…

Thermometer ● 1 Digital Timer ● Gas pressure sensor ● Logger Pro ● Vernier computer interface ● Laptop computer ● 2 Ring stands ● 2 utility clamps ● 3 400 ml Glass beakers ● 1 Small plastic shoe container ● 6 Sprigs of Elodea ● 1 Hot plate ● 1 Small plastic pan ● Ice to fill the pan ● DI Water Method First, turn the hot plate on to start the heating process, careful not to touch it after it is on. Power on the computer and connect the gas pressure sensor to the interface (Lab…

a container, this is known as its pressure. Pressure varies based on temperature and volume. Many gas laws were used within this experiment, such as the Ideal Gas Law, Boyle’s Law, Charles’s Law, and Avogadro’s Law. The Ideal Gas Law is simply the combination of all the simple gas laws, Boyle’s Law, Charles’ Law, and Avogadro’s Law [which combines all of the properties of a gaseous sample].2 Boyle’s…

There are many reasons a scholar may cheat. However, the most prominent reason is the pressure to meet academic standards. Students have the fear of failing. Some students struggle with certain subjects no matter how hard they study and try in that subject. While, others have problems at home or “don’t have time.” The fear of being “average” is the next reason many my cheat. The students driven who want to pursue college may feel the need to cheat to help make sure they get the higher grades…

the Northern and Southern Hemispheres alongside with explaining the major wind belts. Material: • Map of North America with longitude and latitude • Drawing compass Procedure: 1. View the map from the lab given. The map represents the barometric pressures at 5000 feet in North America on a precise day in February. 2. Use the Web to get another map of North America that covers the same approximate area shown in the map given in the lab and is noted with latitude and longitude. Keep in mind at…

3.2. Initial and Boundary Conditions. The pipe is subject to atmospheric pressure Po at time zero this represented initial condition . Boundary condition represented as at the pipe inlet profiles, uniform pressure Pinlet and its value change with concentration of nanofluid [φ%] and inlet temperature T0 = 60 ºC can be measured for all experimental . On the pipe wall, the pressure was atmospheric pressure Po . Moreover, flow and thermal fields are assumed symmetrical with respect to…

liquid and its velocity. The capillary pressure at porous media is defined as the difference between pressure in the liquid and vapor phase. Mass conservation for liquid phase is as follow: (18) (∂(εsρ_l))/∂t+∇.(ρ_l u ⃗_l )=S_(g-l) Darcy law can be used for liquid momentum equation in porous media; therefore, momentum equation is reduced and can be expressed by: (19) u ⃗_l=-K_l/μ_l ∇p_l Also, the liquid pressure can be extracted from definition of capillary pressure. (20) p_c=p_g-p_l=f(s)…

Moreover, the use of CT also differs according to types of activity. Higher pressure is required to the skin during exercise, and compatibly lower pressure needs to be applied during relaxation time cite{evers99, partsch2008classification, mosti2008influence}. It means normal sports bandage cannot be used because they have an inhibitive effect on the lymph circulation…
