Exam #1 Practice Questions True or False: Liquid oxygen should have a larger surface tension than liquid bromine (assuming T and P are the same for both liquids). False: Surface tension of liquids increase as Intermolecular Force strength increases. Both O2 and Br2 are non-polar molecules, and have only dispersion forces. Those dispersion forces are stronger for Br2, however, since it has many more electrons (70 vs. 16) than does O2.

Solid oxygen A total of six different phases of solid oxygen are known to exist: 1  α-phase: light blue — forms at 1 atm below 23.8 K, monoclinic crystal structure. 2  β-phase: faint blue to pink — forms at 1 atm below 43.8 K, rhombohedral crystal structure, (at room temperature and high pressure begins transformation to tetraoxygen).rom Wikipedia, the free encyclopedia. Solid oxygen is also used colloquially to refer to oxidizers such as perchlorates, chlorates, or iodine pentoxide from which oxygen can be produced. Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F).

- Atmospheric and hydrostatic pressure-Henry's Law states that the amount of oxygen which will remain dissolved in a volume of water, at constant temperature, is proportional to the ambient pressure of oxygen gas with which it is in equilibrium (CREM, 1987).tmospheric and hydrostatic pressure-Henry's Law states that the amount of oxygen which will remain dissolved in a volume of water, at constant temperature, is proportional to the ambient pressure of oxygen gas with which it is in equilibrium (CREM, 1987).

MADMAN BIOLOGY Water has a high surface tension, that is, it resists distortion at its surfaces (water-air, water-oil, water-solid). When a detergent is added, surfactant molecules accumulate near the surface of the water because. the non-polar (hydrophobic) tail of the surfactant wants to get away from the water.

- Give a reason for the fact that water, the hydride of oxygen, is a liquid at room temperature while the hydride of sulfur (the next member of Group 16) is a gas? (1.) Hydrogen fluoride is a liquid at room temperature and a weak acid but hydrogen chloride is a gas and a strong acid. Explain these facts. (2.) For similar reasons water and ammonia have unexpected properties.

surfactant Surfactant prevents this collapse by reducing the surface tension of the fluids that line the lungs and helping to equalize the pressures between large and small air spaces. Surface tension is a measure of the attraction molecules of a fluid have for each other.f the surface tension is lowered, the attraction among molecules of the fluid is decreased and the surface area of the fluid increases. For example, if a drop of detergent is added to a drop of water, the detergent reduces the surface tension and the drop of water flattens out.

Surface Tension and Water Examples of surface tension. Walking on water: Small insects such as the water strider can walk on water because their weight is not enough to penetrate the surface. Floating a needle: A carefully placed small needle can be made to float on the surface of water even though it is several times as dense as water.

Occupational Safety and Health Administration Leakage.. Where oxygen is stored as a liquid, noncombustible surfacing shall be provided in an area in which any leakage of liquid oxygen might fall during operation of the system and filling of a storage container. For purposes of this paragraph, asphaltic or bituminous paving is considered to be combustible.

Surface Tension and Water This surface layer (held together by surface tension) creates a considerable barrier between the atmosphere and the water. In fact, other than mercury, water has the greatest surface tension of any liquid.

11-9. Cohesion and Adhesion in Liquids: Surface Tension and Capillary Action Table 1 lists values of γ for some liquids. For the insect of Figure 2(a), its weight w is supported by the upward components of the surface tension force: w=γLsinθ, where L is the circumference of the insect’s foot in contact with the water. Figure 3 shows one way to measure surface tension. The liquid film exerts a force on the movable wire in an attempt to reduce its surface area. The magnitude of this force depends on the surface tension of the liquid and can be measured accurately. Surface tension is the reason why liquids form bubbles and droplets.

Oxygen (O) and water The oxygen atom is very reactive and forms oxides with virtually all other elements, with the exception of helium, neon, argon and krypton. There are also a large amounts of compounds that react with water.Solubility of oxygen and oxygen compounds. Water solubility of oxygen at 25 o C and pressure = 1 bar is at 40 mg/L water. In air with a normal composition the oxygen partial pressure is 0.2 atm.This results in dissolution of 40.olubility of oxygen and oxygen compounds.

- Prolonged exposure to low dissolved oxygen levels (less than 5 to 6 mg/l oxygen) may. not directly kill an organism, but will increase its susceptibility to other environmental stresses. Exposure to less than 30% saturation (less than 2 mg/l oxygen) for one to four days may kill most. of the aquatic life in a system.oth the partial pressure and the degree of saturation of oxygen will change with altitude. Finally, gas solubility decreases as pressure decreases. Thus, the amount of oxygen absorbed in water decreases as altitude increases because of the decrease in relative pressure.

Surface Tension and Bubbles Surface Tension and Droplets: Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer.

- Surface tension is a property that allows the surfaceof a liquid to behave somewhat as a trampoline does. When a person stands on atrampoline, the trampoline stretches downward a bit and, in so doing, exerts an upwardelastic force on the person. This upward force balances the person’s weight.herefore, the weight of the heaviest needlethat can be used in this demonstration isWL== °=×2 2 0073 0032 0 4 7 10 γcos. . cos .θ N/m m N −3 Figure 4 A needle can float on a water surface, because the surface tension of the watercan lead to forces strong enough to support the needle’s weight.

Why is the boiling point of oxygen so low? Report Abuse. Boiling points depend on the strength of intermolecular bonding. Since Oxygen gas is held together by London dispersion forces, the bonding should be low. Also, the lower the number of electrons, the lower the London Dispersion forces. Since the strength of bonds in Oxygen is so low, so is its boiling point. helloeverybody! · 8 years ago.

Viscosity and surface tension A needle placed carefully on water, however, can be supported by the surface tension-the liquid responds in a way similar to a stretched membrane. Try it at home-see what you can get to float on water. One way to think of surface tension is in terms of energy. The larger the surface, the more energy there is.
